Name of the Vulnerable Software and Affected Versions WatchGuard Single Sign-On Client versions through 12.7

Description The issue is related to improper handling of exceptional conditions in the WatchGuard Single Sign-On Client on Windows, causing the client to crash when handling malformed commands. An attacker with network access to the client could create a denial of service condition for the Single Sign-On service by repeatedly issuing malformed commands.

Recommendations For versions through 12.7, update to a version that fixes the improper handling of exceptional conditions to prevent the client from crashing due to malformed commands. As a temporary workaround, consider restricting network access to the Single Sign-On Client to minimize the risk of exploitation.
