AI-analyzed exploit summary This Metasploit module exploits a DLL hijacking vulnerability in Canon TR150 printer drivers (CVE-2021-38085) to achieve local privilege escalation to NT AUTHORITY\SYSTEM by overwriting a DLL in a writable directory and triggering its execution via the PrintIsolationHost.exe process.
Description
The Canon TR150 print driver through 3.71.2.10 is vulnerable to a privilege escalation issue. During the add printer process, a local attacker can overwrite CNMurGE.dll and, if timed properly, the overwritten DLL will be loaded into a SYSTEM process resulting in escalation of privileges. This occurs because the driver drops a world-writable DLL into a CanonBJ %PROGRAMDATA% location that gets loaded by printisolationhost (a system process).
