| Titel | Nor2-io heim-mcp <=0.1.3 Command Injection |
|---|
| Beschreibung | A command injection vulnerability exists in Nor2-io/heim-mcp due to unsafe use of child_process.exec when constructing Heim CLI 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.exec:
new_heim_application: interpolates path, openApiPath, name, version, language, and basePath parameters
deploy_heim_application: interpolates path parameter
deploy_heim_application_to_cloud: interpolates path parameter
Because exec 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 path 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.
