Description
Wazuh is a free and open source platform used for threat prevention, detection, and response. Prior to 4.12.0, a buffer over-read occurs in w_expression_match() when strlen() is called on str_test, because the corresponding buffer is not being properly NULL terminated during its allocation in OS_CleanMSG(). A compromised agent can cause a READ operation beyond the end of the allocated buffer (which may contain sensitive information) by sending a specially crafted message to the wazuh manager. An attacker who is able to craft and send an agent message to the wazuh manager can cause a buffer over-read and potentially access sensitive data. This vulnerability is fixed in 4.12.0.

Executive Summary

This vulnerability is a buffer over-read in Wazuh versions prior to 4.12.0. It occurs because a buffer is not properly NULL terminated during allocation, leading to strlen() reading beyond the intended buffer boundary. A compromised agent can send a specially crafted message to the Wazuh manager, causing it to read beyond the allocated buffer and potentially access sensitive information.

Impact Analysis

If exploited, this vulnerability allows an attacker who can send messages to the Wazuh manager to cause a buffer over-read, potentially exposing sensitive data contained in memory beyond the intended buffer. This could lead to unauthorized access to sensitive information.

Mitigation Strategies

The vulnerability is fixed in Wazuh version 4.12.0. To mitigate this vulnerability, you should upgrade your Wazuh installation to version 4.12.0 or later.
