Summary

WatchGuard Agent before 1.25.14.0000 assigns incorrect permissions to its log directory, which is CWE-732. A local, authenticated non-administrative user can create, modify, append to, or delete the agent's log files and write other files into that directory. An attacker can use this to tamper with or destroy security logs and to place executable content in a directory owned by a privileged service.

Description from the CNA

An incorrect permission assignment vulnerability in the WatchGuard Agent's log directory allows a local, authenticated non-administrative user to create, modify, append to, or delete the agent's log files and write other files into the directory. This allows an attacker to tamper with or destroy the agent's security logs and stage further local attacks by placing executable content in a directory owned by a privileged service.
