CVE-2021-38085
High
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).
