CVE-2025-49642

Local code execution via writable library search path

Published Dec 1, 2025 · Updated Dec 1, 2025

Untrusted search path in affected AIX Zabbix Agent builds allows local users to execute code through a library placed in /home/cecuser. The AIX agent loader searches /home/cecuser for libraries without restricting that directory to trusted writers. A local account with write access can substitute code that runs in the agent's security context; the vendor has not named the library involved.
