Add io.LimitReader with 5MB limit to prevent memory exhaustion and
fix ignored error in queryShodanHost. The error from io.ReadAll was
previously being discarded with _, which could mask read failures.
Add io.LimitReader with 5MB limit to all HTTP response body reads
to prevent potential memory exhaustion from maliciously large responses.
Affected files:
- pkg/scan/cms.go
- pkg/scan/subdomaintakeover.go
- pkg/scan/js/scan.go
- pkg/scan/js/supabase.go
Move regex compilation from inside functions to package level to avoid
recompiling on every function call. This improves performance by
compiling the regex patterns once at package initialization.
- Move jwtRegex to package level in supabase.go
- Move nextPagesRegex to package level in next.go
- Use strings.Builder instead of string concatenation in next.go
Add module system integration allowing users to run YAML-defined security
modules via CLI flags. Implements --list-modules to display available modules,
and supports running modules by ID, tags, or all at once.
- create detector interface and registry for extensibility
- extract detectors to separate files: backend.go, frontend.go, cms.go, meta.go
- reduce detect.go from 785 lines to 178 lines (pure orchestrator)
- export VersionMatch and ExtractVersionOptimized for detector use
- create result.go with NewFrameworkResult and WithVulnerabilities helpers
- add url validation to New() for early error detection
- add sif_test.go with main package tests
- update detect_test.go to use external test package pattern
introduce ScanResult interface and generic NewModuleResult constructor
for compile-time type safety when creating module results.
- add pkg/scan/result.go with ScanResult interface and named slice types
- add typed shodanMetadata struct to replace map[string]interface{}
- refactor supabase.go with typed response structs and json.RawMessage
- add ResultType() methods to all scan result types
- update sif.go to use NewModuleResult generic constructor
this provides type safety without breaking JSON serialization.
move CVEEntry struct and knownCVEs map to cve.go for better
organization. this reduces detect.go by another 170 lines and makes
the CVE database easier to maintain and extend.
move version extraction patterns to version.go and compile them at init
time instead of recompiling on every check. this significantly improves
framework detection performance.
- add version.go with pre-compiled regex patterns for all frameworks
- update detect.go to use extractVersionOptimized
- remove duplicate extractVersionWithConfidence and isValidVersion functions
- add io.LimitReader to prevent memory exhaustion on large responses
- update tests to use the optimized version extraction
implement channel-based work distribution with generics for type-safe
concurrent processing, includes run, runwithfilter, and foreach methods
with comprehensive test coverage
replace o(n) slice iteration with map lookups for checking duplicates,
preallocate result slices, reduce lock hold time by separating map check
from result append
replace errors.new(fmt.sprintf()) with fmt.errorf, use strings.builder
instead of string concatenation in loop, fix defer in loop issue,
preallocate slices where size is estimable
replace per-write file open/close with cached file handles and buffered
writers for significantly reduced i/o overhead. adds flush and close
methods for proper cleanup at program exit.
- fix version detection to validate reasonable version numbers (major < 100)
- remove overly permissive patterns that caused false positives
- add comprehensive framework contribution documentation to CONTRIBUTING.md
- document signature patterns, version detection, and CVE data format
- add configuration documentation for flags and env vars
- outline future enhancements for community contributions
- use math.Exp instead of custom exp implementation
- add more framework signatures: next.js, nuxt.js, wordpress, drupal,
symfony, fastapi, gin, phoenix
- fix header detection to check both header names and values
- simplify version detection (remove unnecessary padding)
- add comprehensive test suite for framework detection
- fix formatting in dork.go
- weighted signature matching for more accurate framework detection
- sigmoid normalization for confidence scores
- version detection with semantic versioning support
- header-only pattern
adds a new --lfi flag for local file inclusion vulnerability scanning:
- tests common lfi parameters with directory traversal payloads
- detects /etc/passwd, /etc/shadow, windows system files
- identifies php wrappers and encoded content
- supports various bypass techniques (null bytes, encoding)
closes#4
- remove duplicate SubdomainTakeover call that ran twice when both
dns scan and --st flag were enabled
- add comprehensive tests for config settings defaults and behavior
- fix formatting in dork.go
closes#1
adds a new --shodan flag that queries the shodan api for information
about the target host. requires SHODAN_API_KEY environment variable.
features:
- resolves hostnames to ip addresses
- queries shodan host api for reconnaissance data
- displays organization, isp, location, ports, services, and vulns
- logs results to file when logdir is specified
closes#2
- update badges to point to vmfunc/sif
- replace ascii art with banner image
- fix header check action to check first 5 lines
- remove obsolete LICENSE.md
