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.

AI Powered Q&A
Can you explain this vulnerability to me?

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.


How can this vulnerability impact me? :

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.


What immediate steps should I take to mitigate this vulnerability?

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.
