An issue was discovered in DisplayLink Core Software Cleaner Application 8.2.1956. When the drivers are updated to a newer version, the product launches a process as SYSTEM to uninstall the old version: cl_1956.exe is run as SYSTEM on the %systemroot%\Temp folder, where any user can write a DLL (e.g., version.dll) to perform DLL Hijacking and elevate privileges to SYSTEM.
The product searches for critical resources using an externally-supplied search path that can point to resources that are not under the product's direct control.
