SYSTEM privilege escalation via log rollover file move
Published Dec 1, 2023 · Updated Nov 26, 2024
Improper privilege management in HuddlyCameraService before 8.0.7, excluding 7.99, allows local users to gain SYSTEM privileges. During log rollover, RollingFileAppender.DeleteFile follows attacker-controlled junctions and symbolic links and calls MoveFileEx without impersonating the user. A low-privileged Windows user must win the file-operation race; the resulting SYSTEM-context move can place a writable DLL in a privileged directory for execution after reboot.
