How the Exploit Works

The exploit takes advantage of a path traversal vulnerability in AstrBot’s development framework. An attacker can manipulate file paths to access files that should be out of reach, leading to the disclosure of sensitive information. This information can include API keys for LLM providers, account passwords, and other sensitive data that can be used to compromise the system or lead to data breaches.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited using a malicious file path in the request:

GET /dashboard/../../../etc/passwd HTTP/1.1
Host: target.example.com
Content-Type: application/json

In this example, the attacker is attempting to access the `/etc/passwd` file, which is typically restricted from public access. This file could contain sensitive information that could be exploited for further attacks.

Mitigation

Users are advised to upgrade to version v3.5.13 or later where the issue has been addressed. In the meantime, users can edit the `cmd_config.json` file to disable the dashboard feature as a temporary workaround. Employing a WAF/IDS could also provide temporary mitigation against this vulnerability. However, it is highly recommended to apply the vendor patch for a complete resolution.
