CVE-2026-7215 Details
Description
A security flaw has been discovered in egtai gmx-vmd-mcp up to 0.1.0. This issue affects the function launch_vmd_gui_tool of the file mcp_server.py of the component VMD Launch Handler. The manipulation of the argument structure_file/trajectory_file results in command injection. The attack may be launched remotely. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
A command injection vulnerability has been identified in Egtai GMX-VMD-MCP versions through 0.1.0. The issue arises in the VMD Launch Handler component, specifically within the 'launch_vmd_gui_tool' function of 'mcp_server.py'. The vulnerability allows for arbitrary command execution on the host by manipulating the 'structure_file' and 'trajectory_file' arguments. This exploitation can be performed remotely, and a public exploit is available.
It is recommended to avoid using 'os.system()' for executing commands with user-supplied file paths. Instead, use 'subprocess.run()' or 'create_subprocess_exec' to execute commands safely without a shell. Additionally, normalize and validate file paths before use, and implement regression tests to ensure that similar vulnerabilities do not reoccur.
