Summary

Wazuh authd contains a heap-buffer overflow vulnerability that allows attackers to cause memory corruption and malformed heap data by sending specially crafted input. This can trigger a denial of service condition, resulting in low availability impact to the authentication daemon.

Risk Assessment

An attacker could remotely crash the authentication daemon, disrupting login and agent management processes in Wazuh. The availability impact is rated low but may hinder security monitoring operations.

Recommendation

Update Wazuh to a version containing the authd heap-buffer overflow fix. Until updated, restrict network access to the authentication daemon port.
