Comodo Antivirus 12.2.2.8012 has a quarantine flaw that allows privilege escalation. To escalate privilege, a low-privileged attacker can use an NTFS directory junction to restore a malicious DLL from quarantine into the System32 folder.
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
