| Título | AstrBotDevs AstrBot 4.23.6 Path Traversal (CWE-22) |
|---|
| Descripción | # Technical Details
A Path Traversal exists in the `/api/skills/delete` API endpoint in AstrBot.
The application fails to sanitize the `name` parameter provided during the skill deletion process. An authenticated attacker can supply a path traversal payload in the JSON body (e.g., `{"name": "../target_directory"}`) to delete arbitrary directories on the underlying host filesystem, bypassing intended directory restrictions.
# Vulnerable Code
File: [Needs Manual Input]
Method: delete_skill (API: /api/skills/delete)
Why: The API endpoint uses the attacker-controlled `name` parameter to construct a directory path for deletion without proper normalization or boundary checks to ensure the path remains within the skills folder.
# Reproduction
1. Authenticate to the AstrBot Dashboard via `/api/auth/login` to obtain a JWT token.
2. Send a `POST` request to the `/api/skills/delete` endpoint.
3. Supply a JSON payload targeting a directory outside the intended scope using path traversal: `{"name": "../poc_target_exploit"}`.
4. Observe that the arbitrary directory on the server filesystem is successfully deleted.
# Impact
- Arbitrary directory deletion, resulting in potential data loss.
- High risk of Denial of Service (DoS) by removing critical application or system directories. |
