What is CVE-2025-62792?

The Wazuh platform is susceptible to a buffer over-read vulnerability that occurs within the function w_expression_match(). This issue arises due to improper NULL termination of a buffer during its allocation in OS_CleanMSG(), leading to the potential for a compromised agent to exploit this flaw. By sending a specially crafted message to the Wazuh manager, an attacker may cause a READ operation beyond the end of the allocated buffer, thereby gaining unauthorized access to sensitive information. This vulnerability has been rectified in version 4.12.0.
