Summary

Wazuh Manager authd service in wazuh-manager packages through version 4.7.3 contains an improper restriction of client-initiated SSL/TLS renegotiation vulnerability, allowing remote attackers to cause a denial of service by sending excessive renegotiation requests.

Risk Assessment

Risk of CPU exhaustion and unavailability of authd service, potentially disrupting Wazuh operations.

Recommendation

Upgrade Wazuh to a version newer than 4.7.3 or apply renegotiation limits.

Other vulnerabilities in Wazuh Manager

CVE-2026-39359High
A logic flaw in Wazuh Manager versions 4.0.0-4.10.3 and 4.11.0-4.14.4 affects the enrollment daemon (authd) and synchronization daemon (remoted). The authd process allows agents to select a group during enrollment without filtering path traversal sequences like "..", enabling access to files outside the intended directory. Sensitive files such as client.keys, ossec.conf, and internal certificates are exposed to the attacker.

Original NVD description (English source)

Wazuh Manager authd service in wazuh-manager packages through version 4.7.3 contains an improper restriction of client-initiated SSL/TLS renegotiation vulnerability that allows remote attackers to cause a denial of service by sending excessive renegotiation requests. Attackers can exploit the lack of renegotiation limits to consume CPU resources and render the authd service unavailable.
