| Titel | kazuph mcp-docs-rag <= 0.5.0 Command Injection |
|---|
| Beschreibung | A command injection vulnerability exists in mcp-docs-rag due to unsafe use of child_process.execAsync when constructing Git and Wget commands with user-controlled input. Successful exploitation allows attackers to execute arbitrary shell commands with the privileges of the MCP server process. The following MCP tools construct command strings using user-supplied parameters and execute them via child_process.execAsync:
add_git_repository: interpolates repository_url and subdirectory parameters
add_text_file: interpolates file_url parameter
Because execAsync invokes commands through a system shell, specially crafted input containing shell metacharacters (such as `;`, `&`, or `|`) may be interpreted as additional commands rather than treated as data.
For example, an attacker could supply a malicious value in repository_url to inject arbitrary shell commands, which would then be executed with the privileges of the MCP server process.
The vulnerability results from shell-based command execution combined with direct interpolation of untrusted input. In MCP environments, LLM-generated tool parameters influenced by external content may trigger execution of injected commands without direct local user interaction.
