CVE-2021-44049Public exploit

Privilege escalation via Temp executable hijacking

Published Jan 15, 2022 · Updated Aug 4, 2024

Local privilege escalation in CyberArk Endpoint Privilege Manager 11.5.3.328 and earlier allows local users to execute code with elevated rights. The EPM agent invokes Procmon64.exe from the user-writable Temp directory without ensuring that the executable is trusted. A low-privileged local user who plants a Trojan horse under that name can have EPM run it with elevated privileges, enabling arbitrary privileged actions.
