Description
gemini-mcp-tool execAsync Command Injection Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of gemini-mcp-tool. Authentication is not required to exploit this vulnerability. The specific flaw exists within the implementation of the execAsync method. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of the service account. Was ZDI-CAN-27783.

Executive Summary

This vulnerability is a critical remote code execution flaw in the gemini-mcp-tool's execAsync method. It occurs because the method does not properly validate a user-supplied string before using it to execute a system call. This allows remote attackers to execute arbitrary code on the affected system without needing to authenticate. [1]

Impact Analysis

Exploitation of this vulnerability allows attackers to run arbitrary code with the privileges of the service account running gemini-mcp-tool. This can lead to a full compromise of the system's confidentiality, integrity, and availability, potentially allowing attackers to control the affected system remotely. [1]

Compliance Impact

This vulnerability allows remote attackers to execute arbitrary code without authentication, potentially leading to full compromise of confidentiality, integrity, and availability of the affected system. Such a compromise can result in unauthorized access to sensitive data, which may lead to violations of compliance requirements under standards like GDPR and HIPAA that mandate protection of personal and health information.
