CyberRota Analysis
AI-GeneratedThe vulnerability affects Wazuh versions from 1.0.0 to 4.14.6 and 5.0.0-beta2, specifically in the HandleSecureMessage() function, which improperly handles stack buffer pointers during message processing. An attacker could exploit this flaw to trigger a stack out-of-bounds write, potentially crashing the remoted daemon and disrupting agent communications. Organizations using affected versions of Wazuh should prioritize upgrading to the patched versions 4.14.6 or 5.0.0-beta2 to mitigate this risk.

Original NVD Description
Wazuh is a free and open source platform used for threat prevention, detection, and response. From 1.0.0 until 4.14.6 and 5.0.0-beta2, HandleSecureMessage() in src/remoted/secure.c passes a pointer inside its stack buffer to ReadSecMSG(), and src/os_crypto/shared/msgs.c decompresses up to OS_MAXSTR bytes at that offset. For an encrypted agent message on TCP port 1514 that expands to 65,536 bytes, os_zlib_uncompress() writes a terminating null byte beyond the end of the destination buffer. The resulting stack out-of-bounds write in the root-level remoted daemon can crash message processing and disrupt agent communications. This issue is fixed in versions 4.14.6 and 5.0.0-beta2.
