SYSTEM privilege escalation via junction-following quarantine restore
Published Mar 18, 2020 · Updated Aug 5, 2024
Privilege escalation in Adaware Antivirus 12.6.1005.11662 and 12.7.1055.0 allows local users to execute code with SYSTEM privileges. Its quarantine restore operation follows an attacker-created NTFS directory junction and writes a quarantined malicious DLL into the Windows System32 directory. Exploitation requires low-privileged local access to plant and quarantine the DLL and redirect its restore path; the protected-directory write enables SYSTEM-level code execution.
