CVE-2026-32983: CWE-276 Incorrect Default Permissions in Wazuh wazuh-manager
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.
AI Analysis
Technical Summary
The Wazuh Manager authd service in wazuh-manager versions up to 4.7.3 improperly restricts client-initiated SSL/TLS renegotiation. This allows remote attackers to send excessive renegotiation requests, leading to resource exhaustion and denial of service. The vulnerability is categorized under CWE-276, which relates to incorrect default permissions or restrictions. No patch or remediation information is currently provided, and no known exploits are reported in the wild.
Potential Impact
Remote attackers can exploit this vulnerability to cause a denial of service by overwhelming the authd service with excessive SSL/TLS renegotiation requests. This results in high CPU usage and unavailability of the authd service, potentially disrupting Wazuh Manager operations.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider limiting exposure of the authd service to untrusted networks and monitoring for unusual renegotiation activity if possible.
