CVE-2025-57625Public exploit

SYSTEM code execution via current-directory DLL search

Published Sep 16, 2025 · Updated Sep 16, 2025

DLL hijacking in CYRISMA Sensor before 444 for Windows allows local users to execute arbitrary code as NT AUTHORITY\SYSTEM. DataSpotliteAgent.exe searches its current directory for missing DLLs, including CRYPTBASE.dll, and loads an attacker-planted library. A low-privileged local account with write access to that directory is sufficient, and the Cyrisma_Agent service executes the library with SYSTEM privileges.
