CVE-2018-7884

Name of the Vulnerable Software and Affected Versions: DisplayLink Core Software Cleaner Application version 8.2.1956

Description: An issue was discovered in the DisplayLink Core Software Cleaner Application. When the drivers are updated to a newer version, the product launches a process as SYSTEM to uninstall the old version. This process, 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.

Recommendations: For DisplayLink Core Software Cleaner Application version 8.2.1956, as a temporary workaround, consider restricting write access to the %systemroot%Temp folder to minimize the risk of exploitation.
