Security Advisories Relating to Symantec Products - Symantec Messaging Gateway
Management Console Reflected XSS

Messaging Gateway Management Interface Reflective XSS - Medium

Symantecs Messaging Gateway management console is susceptible to a reflected 
cross-site scripting (XSS) issue found in one of the administrative interface
pages. Successful exploitation could result in potential session hijacking or
unauthorized actions directed against the console with the privileges of the 
targeted users browser.

Product(s) Affected

Product				Version		Solution

Symantec Messaging Gateway	10.x - 10.5.1	Symantec Messaging Gateway 10.5.2


Symantec was notified of a reflected XSS issue impacting Symantecs Messaging 
Gateway 10.x management console.

A reflected XSS issue exists in one of the interface pages used to manage the
gateway as a result of insufficient validation/sanitation of user input. 
Successful targeting of this weakness could allow an unauthorized individual 
to steal the browser cookies or hijack the browser session being used to 
manage the console. This could potentially allow the unauthorized individual 
authorized user-level access to the management console. The management console
normally allows access to only specified users/administrators with varying 
levels of access depending on their requirements.

In a typical installation the Symantec Messaging Gateway management interface
should not be accessible external to the network environment and access should
be restricted to specified users/administrators. Web browsers used by 
authorized users to manage Symantec Messaging Gateway should never be used for
casual browsing of external web sites during an administrative session. These
restrictions would greatly reduce exposure to external attempts against this 
type of issue.

A malicious but authorized non-privileged network user or an external attacker
would need to successfully entice an authorized management console user to 
visit a malicious web site or click on a malicious HTML link in an email in 
any attempts to take advantage of this issue.

Symantec Response

Symantec engineers verified this issue in Symantec Messaging Gateway 10.x. 
Symantec strongly recommends Symantec Messaging Gateway customers update to 
the latest release of Symantec Messaging Gateway, 10.5.2. Symantec knows of no
exploitation of or adverse customer impact from this issue.

Symantec Messaging Gateway 10.5.2 is currently available through customers 
normal update channels.

Best Practices

As part of normal best practices, Symantec strongly recommends:

* Restrict access to administration or management systems to 
privileged users.

* Disable remote access if not required or restrict it to 
trusted/authorized systems only.

* 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 patches.

* 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 latent
