WatchGuard has released critical security fixes for Fireware OS to address a flaw in its VPN implementation that is currently being exploited in the wild. The vulnerability allows for unauthorized access to the network through the VPN service, bypassing standard authentication checks.
Business Impact
A compromised VPN is a direct entry into the internal network. For SMEs and branch offices that rely on WatchGuard for their secure perimeter, this flaw represents an immediate threat of lateral movement, data theft, or ransomware deployment.
Why It Happened
The flaw involves improper handling of session tokens during the VPN handshake process. This was discovered and weaponized by threat actors targeting remote access infrastructure just as holiday travel increases.
Recommended Executive Action
Mandate an immediate update to Fireware OS for all WatchGuard appliances. Verify that no unauthorized administrative accounts have been created on the devices within the last 48 hours and rotate VPN shared secrets if possible.
