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.
AnalysisAI
gemini-mcp-tool has a command injection in execAsync allowing remote code execution on systems using the Gemini AI MCP integration.
Technical ContextAI
The gemini-mcp-tool has a CWE-78 command injection in the execAsync function, part of a pattern of command injection vulnerabilities across MCP server implementations.
RemediationAI
Update the tool. Use parameterized command execution instead of shell interpolation.
