Details

Vorota-ai nmap-mcp through commit 3636afa contains an improper allowlist validation vulnerability in the scan_vulnerabilities tool that lets callers run blocked NSE script categories. MCP clients or prompt-injected agents can pass categories like exploit, dos, brute, or intrusive to nmap --script, running intrusive, brute-force, exploit, or denial-of-service scripts against scan targets.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
