Assigner: AMZN

Description
An argument injection issue in the diff scan operation in AWS security-agent-mcp-server before version 0.2.0 might allow context-dependent threat actors to create, overwrite, or truncate arbitrary files on the host outside the intended workspace directory via a crafted reference value supplied to the diff scan operation. To remediate this issue, users should upgrade to version 0.2.0.

Executive Summary

This is an argument injection vulnerability in AWS security-agent-mcp-server's diff scan operation. It allows a crafted reference value to be misinterpreted as a command-line option instead of a revision. This enables attackers to create, overwrite, or truncate arbitrary files on the host system outside the intended workspace directory, bypassing the server's confinement controls.

Detection Guidance

Detection involves checking the version of AWS security-agent-mcp-server. Run 'security-agent-mcp-server --version' to verify if the installed version is below 0.2.0. Additionally, monitor file system changes outside intended directories during diff scan operations.

Impact Analysis

An attacker could exploit this to modify or delete critical files on your system, potentially leading to data loss, system instability, or unauthorized access. It may also allow attackers to escalate privileges if they overwrite system or application files.

Compliance Impact

This vulnerability could lead to unauthorized file access or modification, violating data integrity and confidentiality requirements in GDPR and HIPAA. It may result in non-compliance due to potential data breaches or loss of protected health information.

Mitigation Strategies

Immediately upgrade AWS security-agent-mcp-server to version 0.2.0 or later. Avoid running diff scans against untrusted repositories. Run the server with least privileges and in an isolated environment until patched.
