Solution

Apply an Update

Symantec Web Gateway users should upgrade to 5.2.1 or later. Users can click “Check for Updates” on the Administration->Updates page to receive the fixed version. If you are unable to upgrade, please consider the following workaround.

---

Restrict Access

As a general good security practice, only allow connections from trusted hosts and networks. Note that restricting access does not prevent XSS or SQLi attacks since the attack comes as a request from a legitimate user’s host. Restricting access would prevent an attacker from accessing the web interface using stolen credentials from a blocked network location.
