LOW 2.1

DescriptionCVE.org

A vulnerability was determined in AstrBotDevs AstrBot up to 4.22.1. Impacted is the function add_mcp_server of the file astrbot/dashboard/routes/tools.py of the component MCP Endpoint. This manipulation of the argument command causes command injection. The attack is possible to be carried out remotely. The exploit has been publicly disclosed and may be utilized. The project was informed of the problem early through an issue report but has not responded yet.

AnalysisAI

Command injection in AstrBot's MCP endpoint handler (add_mcp_server function) allows authenticated remote attackers to execute arbitrary system commands via the command parameter. Versions up to 4.22.1 are affected. The vulnerability is publicly disclosed with exploit code available on GitHub, and the vendor has not released a patch despite early notification.

Technical ContextAI

The vulnerability exists in the MCP (Model Context Protocol) endpoint implementation within astrbot/dashboard/routes/tools.py. The add_mcp_server function fails to properly sanitize or escape the command argument before passing it to system execution, enabling classic command injection (CWE-77). MCP is a protocol for integrating external tools and services into AI assistants. The affected component processes user-supplied command strings without validation, allowing attackers to inject shell metacharacters (pipes, semicolons, command substitution syntax) that are interpreted by the underlying shell interpreter. CPE cpe:2.3:a:astrbotdevs:astrbot identifies all AstrBot releases up to version 4.22.1.

RemediationAI

No vendor-released patch identified at time of analysis. Users should immediately upgrade to a patched version if the vendor releases one, or contact the vendor at https://github.com/AstrBotDevs/AstrBot/ for available security updates. In the interim, implement strong access controls to restrict dashboard access to trusted administrators only, enforce network segmentation to limit dashboard exposure, and monitor MCP endpoint logs for suspicious command patterns. Consider disabling the MCP tool integration if not actively required. The GitHub issue at https://github.com/AstrBotDevs/AstrBot/issues/7169 may contain additional context or community-driven mitigations.
