A vulnerability was reported in Symantec Brightmail Gateway
The vulnerabilities are reported in versions prior to 9.5.x
Symantec’s Brightmail Gateway management console is susceptible to stored cross-site scripting (XSS) issues found in some of the administrative interface pages.
The administrative interface does not properly filter HTML code from user-supplied input before displaying the input. A remote user can cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the Symantec Brightmail Gateway interface and will run in the security context of that interface.
A remote user can access the target user's cookies (including authentication cookies), if any, associated with the Symantec Brightmail interface, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.
Vendor recommendation is to Update to version 10.x
