Title
Fireware OS Missing Command Validation allows Authenticated Arbitrary File Modification as Root
Summary
An external control of file path vulnerability in a WatchGuard Fireware OS firewall diagnostic command allows a remote, authenticated attacker with at least read-only (Device Monitor) privileges and access to the management CLI to create, truncate, or overwrite arbitrary files and modify kernel parameters with root privileges by submitting a specially crafted command. Written content is limited to numeric values.

Title
Fireware OS Stack Buffer Overflow in WireGuard Configuration Allows Remote Code Execution
Summary
A stack-based buffer overflow vulnerability in Fireware OS's WireGuard configuration processing allows a remote attacker that has man-in-the-middle TLS-decrypted access between the Firebox and WatchGuard Cloud to create a Denial of Service condition and potentially execute arbitrary code by tampering with a FireCloud Gateway configuration payload.

Title
WatchGuard Agent Incorrect Permission Assignment in Log Directory Allows Local Log Tampering
Summary
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.
