Name of the Vulnerable Software and Affected Versions Watchguard Firebox versions prior to 10

Description The issue concerns the PPTP VPN service in Watchguard Firebox, where the MS-CHAPv2 authentication handshake generates different error codes depending on whether the username is valid or invalid. This allows remote attackers to enumerate valid usernames.

Recommendations For versions prior to 10, update to version 10 or later to resolve the issue. As a temporary workaround, consider restricting access to the PPTP VPN service until the update is applied.
