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. This issue affects Single Sign-On Client: through 12.7. |
Solution
No solution given by the vendor.
Workaround
An attacker must have already established network access to exploit this vulnerability. WatchGuard recommends using Windows Firewall rules to restrict TCP port 4116 network access to the Single Sign-On Client to only allow connections from the Authentication Gateway (SSO Agent). Windows administrators can use Group Policy objects to add Windows firewall rules to their endpoints.
