DescriptionCVE.org

A vulnerability was determined in Nor2-io heim-mcp up to 0.1.3. Impacted is the function registerTools of the file src/tools.ts of the component new_heim_application/deploy_heim_application/deploy_heim_application_to_cloud. This manipulation causes os command injection. The attack requires local access. The exploit has been publicly disclosed and may be utilized. Patch name: c321d8af25f77668781e6ccb43a1336f9185df37. It is suggested to install a patch to address this issue. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.

AnalysisAI

OS command injection in Nor2-io heim-mcp up to version 0.1.3 allows authenticated local attackers to execute arbitrary system commands via the registerTools function in src/tools.ts, affecting cloud deployment operations. Publicly available exploit code exists, and the vendor released a patched version promptly after disclosure.

Technical ContextAI

The vulnerability stems from insufficient input validation in the registerTools function of heim-mcp's tool registration mechanism (CWE-78: OS Command Injection). The component processes user-supplied input for cloud deployment tool configuration without proper sanitization before passing it to system command execution contexts. The affected product (CPE: cpe:2.3:a:nor2-io:heim-mcp:*:*:*:*:*:*:*:*) is a Model Context Protocol implementation used for deploying Heim applications to cloud infrastructure. The vulnerability exists within the new_heim_application/deploy_heim_application/deploy_heim_application_to_cloud deployment workflow, where attacker-controlled parameters in tool registration can break out of intended command boundaries.

RemediationAI

Vendor-released patch available: upgrade heim-mcp to the version containing commit c321d8af25f77668781e6ccb43a1336f9185df37 or later. The patch is accessible via the official GitHub repository pull request at https://github.com/Nor2-io/heim-mcp/pull/2. Users should apply this patch immediately to all systems running heim-mcp for cloud deployment operations. The vendor confirmed patch availability and professional handling of the disclosure, indicating timely security updates are prioritized. No workarounds are documented; patching is the recommended remediation path.
