Name of the Vulnerable Software and Affected Versions AppGuard Enterprise versions prior to 6.7.100.1

Description The issue allows local users to gain SYSTEM privileges because a repair operation relies on the %TEMP% directory of an unprivileged user. This is due to the creation of a temporary file in a directory with insecure permissions.

Recommendations For versions prior to 6.7.100.1, update to version 6.7.100.1 or later to resolve the issue. As a temporary workaround, consider restricting access to the %TEMP% directory to minimize the risk of exploitation.
