Brightmail Management Interface Stored XSS - Medium
6.2 10 2.0 AV:A/AC:H/AU:M/C:P/I:P/A:P
Symantec's Brightmail Gateway management console is susceptible to stored
cross-site scripting (XSS) issues found in some of the administrative interface
pages. Successful exploitation could result in potential unauthorized
privileged access to the management console.
Product Version Solution
Symantec Brightmail Gateway 9.5.x Move to the latest release
of Symantec Messaging
NOTE: Symantec Brightmail 9.5.x is End of Life. Users should be migrating
away from this release to the latest Symantec Messaging Gateway already
Product(s) Not Affected
Symantec Messaging Gateway 10.x
Symantec was notified of stored XSS issues impacting Symantec's Brightmail
Gateway 9.5.x management console.
Multiple stored XSS issues exist in the interface pages used to manage the
application as a result of insufficient validation/sanitation of user input.
Successfully targeting of these vulnerabilities does require administrator
level access on the management console. A malicious user would require network
access as well as access to an authorized active session on the web-based
In a typical installation the Symantec Brightmail Gateway management interface
should not be accessible external to the network environment. Administrative
systems used to manage Brightmail Gateway should not be used to browse external
web sites. These restrictions greatly reduce exposure to external attempts
against this type of issue.
However, an authorized but non-privileged network malicious user or an external
attacker able to successfully leverage required access to a logged-on
management console account could potentially inject arbitrary scripts into
these vulnerable pages.
Although a low probability of success, a remote attacker could potentially
entice a privileged user to visit a malicious web site. In this scenario the
attacker could attempt to target these stored xss issues by submitting forged
requests on behalf of the authorized user.
Symantec engineers verified these issues in Symantec Brightmail Gateway 9.5.x.
They further confirmed that Symantec Messaging Gateway 10.x is not impacted.
Symantec Brightmail Gateway 9.5.x is an end-of-life product. Symantec strongly
recommends Symantec Brightmail customers update to the latest release of
Symantec Messaging Gateway 10.x. Symantec knows of no exploitation of or
adverse customer impact from this issue.
Symantec Messaging Gateway 10.0.1 is currently available through normal update
As part of normal best practices, Symantec strongly recommends:
Restrict access to administration or management systems to privilll;eged
Disable remote access if not required or restrict it to trusted/authorized
Where possible, limit exposure of application and web interfaces to
trusted/internal networks only.
Keep all operating systems and applications updated with the latest vendor
Follow a multi-layered approach to security. Run both firewall and
anti-malware applications, at a minimum, to provide multiple points of
detection and protection to both inbound and outbound threats.
Deploy network and host-based intrusion detection systems to monitor
network traffic for signs of anomalous or suspicious activity. This may aid
in detection of attacks or malicious activity related to exploitation of
