CVE-2026-74041: Improper Handling of Case Sensitivity in Wazuh wazuh-manager
Description
Wazuh wazuh-manager versions 4.14.3 up to but not including 4.14.8 have a vulnerability due to a case-sensitivity mismatch between the ossec.conf validator and wazuh-logcollector. This flaw allows authenticated users with the manager:update_config privilege to bypass remote-command validation by injecting an uppercase LOG_FORMAT command in localfile configuration, which the collector then executes as root upon reload. The vulnerability has a critical severity with a CVSS score of 9.4.

Technical Analysis
CVE-2026-74041 is a critical vulnerability in Wazuh wazuh-manager where a case-sensitivity mismatch between the ossec.conf validator and the wazuh-logcollector component allows authenticated users with update_config privileges to bypass remote-command validation. Specifically, the flaw permits injection of an uppercase LOG_FORMAT command in localfile configuration, which the logcollector executes with root privileges when reloading the configuration. This affects versions from 4.14.3 up to but excluding 4.14.8.
Potential Impact
An attacker with authenticated access and the manager:update_config privilege can execute arbitrary commands as root on the wazuh-manager host by injecting a specially crafted uppercase LOG_FORMAT command. This leads to a full privilege escalation and remote code execution on the affected system, posing a critical security risk.
Mitigation Recommendations
Upgrade to Wazuh wazuh-manager version 4.14.8 or later where this vulnerability is fixed. Since the vulnerability is due to a case-sensitivity mismatch, applying the official update resolves the issue. No other mitigation or temporary workaround is indicated in the available data.
