CVE-2025-5129Public exploit

Local privilege escalation via MSASN1.dll search path

Published May 24, 2025 · Updated May 28, 2025

Uncontrolled search path handling in Sangfor aTrust 2.3.10.60 allows local users to escalate privileges through MSASN1.dll. The affected MSASN1.dll functionality fails to constrain a search path that local users can influence; the executable and searched location are undisclosed. Exploitation requires local low-privileged access and high attack complexity but no user interaction, and successful exploitation can compromise host confidentiality, integrity, and availability.
