Machine-account hash theft via unchecked UNC paths
Published Nov 21, 2025 · Updated Nov 21, 2025
External path control in Wazuh Agent before 4.13.0 allows remote authenticated users to capture NetNTLMv2 hashes via UNC paths. The SCA policy, osquery log_path and config_path, and FIM directories settings accept network paths and make Windows agents access attacker-controlled SMB shares. Control of the manager or an agent private key is required; a domain-joined target exposes its machine-account hash for relay or lateral movement.
