CVE-2024-32038:
Wazuh Agent vulnerability analysis and mitigation
Overview
Wazuh, a free and open source platform used for threat prevention, detection, and response, contains a buffer overflow vulnerability (CVE-2024-32038) in its wazuh-analysisd component when handling Unicode characters from Windows Eventchannel messages. The vulnerability affects Wazuh Manager versions 3.8.0 and above, and has been fixed in version 4.7.2 (Vendor Advisory).
Technical details
The vulnerability exists within the Analysis Engine service, which listens on TCP port 1514 by default. The specific flaw stems from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. The vulnerability has been assigned a CVSS v3.1 base score of 9.8 (Critical) with the vector string AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, indicating it can be exploited remotely without requiring privileges or user interaction (ZDI Advisory).
Impact
An attacker can leverage this vulnerability to execute arbitrary code in the context of the service account. The critical CVSS score of 9.8 indicates potential severe impacts on system confidentiality, integrity, and availability if successfully exploited (ZDI Advisory).
Mitigation and workarounds
The primary mitigation is to upgrade to Wazuh Manager version 4.7.2 or later. For systems that cannot be immediately updated, the only available workaround is to prevent agents version 3.8 and above from reporting Eventchannel messages (Vendor Advisory).
