Symantec Brightmail Gateway Appliance Cross-site Scripting and Elevation of 


April 23, 2009


Revision History


Remote Access                   Yes (Internal network only)
Local Access                    No
Authentication Required         Yes
Exploit publicly available      No

Symantec Brightmail Gateways Control Center is susceptible to cross-site 
scripting and elevation of privilege vulnerabilities.

Affected Product(s)
Product                         Version                 Solution(s)
Symantec Brightmail Gateway     All prior to 8.0.1      Upgrade to 8.0.1 
                                                        or later

Symantec was notified of cross-site scripting and elevation of privilege issues 
present in the Brightmail Control Center, the web-based management console of 
Symantecs Brightmail Gateway Appliance. The Control Center fails to properly 
filter external client input from users authorized access to the console. 
Scripts used for administrative functions may be susceptible to malicious 
manipulation potentially allowing access to other users sessions, unauthorized 
access to other systems on the internal network or unauthorized information 

In addition, some console functions could potentially be leveraged by an 
authorized but non-privileged Control Center user to gain unauthorized elevated 
access on the Symantec Brightmail Gateway.

Symantec Response
Symantec product engineers have released an update for these issues in all 
affected product versions. Symantec is not aware of any attempts to exploit 
these issues. However, we recommend that all customers upgrade to
non-vulnerable versions to protect against potential attempts to exploit.

How to Obtain the Update
The upgrade is available through the Software Update function of Symantec 
Brightmail Gateway. It can also be downloaded from Symantec File Connect,

System administrators control access to the Symantec Brightmail Control Center 
functionality through role-based administration. Symantec Brightmail 
administrators normally have the rights that could potentially be gained 
through exploiting these issues. However, in some environments users can be 
authorized limited access to Control Center functionality, e.g., a user may be 
allowed limited access to the Control Center to manage their personal 
quarantine messages. This could result in an increased internal threat through 
attempted exploitation of these issues by an authorized but non-privileged 

If customers are unable to upgrade to the fixed version of Symantec Brightmail 
Gateway at this time, Symantec recommends ensuring Brightmail Control Center 
access is restricted to privileged users until the upgrade can be applied.

Best Practices
As part of normal best practices, Symantec strongly recommends:

    * Restrict access to administration or management systems to privileged 
    * Restrict remote access, if required, to trusted/authorized systems only.
    * Run under the principle of least privilege where possible to limit the 
      impact of exploit by threats.
    * 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 vulnerabilities

Symantec would like to thank Dr. Marian Ventuneac, Perot Systems, Ireland, for 
reporting these issues and coordinating with us while Symantec resolved them.
BID: Security Focus, http://www.securityfocus.com, has assigned a Bugtraq ID 
(BID) to these issues for inclusion in the Security Focus vulnerability 
BID 34641 is assigned to the cross-site scripting issues
BID 34639 is assigned to the elevation of privilege issues

CVE: These issues are candidates for inclusion in the CVE list 
(http://cve.mitre.org), which standardizes names for security problems. The 
CVE initiative has assigned
CVE-2009-0063 to the cross-site scripting issues
CVE-2009-0064 to the elevation of privilege issues
