Security Advisories Relating to Symantec Products - Symantec Brightmail Gateway 
Management Console Stored XSS


May 8, 2013




CVSS2		Impact		Exploitability	CVSS2 Vector
Base Score

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(s) Affected

Product				Version			Solution

Symantec Brightmail Gateway	9.5.x			Move to the latest release 
							of Symantec Messaging 
							Gateway 10.x
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

Product				Version
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 
management console. 

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 Response

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 

Best Practices

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 
    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 

    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 vulnerabilities
