Symantec Web Gateway (SWG) 5.2 Appliance management console is susceptible to 
security issues.  Successful exploitation could result in unauthorized command 
execution on or access to the management console.  There is also potential for
unauthorized backend database manipulation. 

Product(s) Affected

Product			Version		Solution

Symantec Web 		5.2 and prior	Symantec Web Gateway 5.2.1
Gateway Appliance
NOTE:  Customers should always ensure they are running the latest data base 
updates available


Symantec was notified of security issues impacting the SWG management console 
that could result in unauthorized access to management console functionality 
and the backend database. The results of successful exploitation could 
potentially range from unauthorized disclosure of sensitive data to possibly 
unauthorized privileged access to the Symantec Web Gateway Appliance.

Unauthenticated arbitrary commands can potentially be injected into application
scripts accessible though the SWG consoles interface.  Successful command 
injection could result in arbitrary command execution with elevated privileges
on the web console. 

SQL injection issues were identified allowing an authenticated SWG 
administrator to make unauthorized database queries.  Successful targeting
could potentially result in arbitrary SQL queries to the backend database 
resulting in unauthorized disclosure of privileged information and/or possibly
unauthorized manipulation of the database.

Some report pages on SWG versions 5.1.x and prior do not properly 
validate/sanitize external input allowing a blind SQL injection with the 
potential to run an unauthorized arbitrary SQL query vice an authorized query.
The 5.1.x version is also impacted by reflected cross-site scripting.  

Successful targeting of these XSS issues could result in hijacking the SWG user
session. Both of these were fully addressed in the release of SWG 5.2 so any 
customers still on a 5.1.x release should migrate to the latest release 
available which is 5.2.1.

In a normal installation, the Symantec Web Gateway management interface should 
not be externally accessible from the network environment.  However, an 
authorized but unprivileged network user or an external attacker able to 
successfully leverage network access could attempt to exploit these weaknesses.

Symantec Response

Symantec engineers confirmed that some of these issues were addressed in the
5.2 release of Symantec Web Gateway and have released an update to 5.2 to
address additional findings. Symantec engineers continue to review related 
functionality to further enhance the overall security of Symantec Web 
Gateway. Symantec has released Symantec Web Gateway 5.2.1, currently 
available to customers through normal support locations.

Customers should ensure they are on the latest release of Symantec Web Gateway 
5.2.1 and running the latest data base update. To confirm customers are running
the latest updates check the "Current Software Version -> Current Version" on 
the Administration->Updates page.  Alternatively, customers can click 
"Check for Updates" on the Administration->Updates page to verify that they are
running the latest software version.

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 

The Symantec Web Gateway software and any applications that are installed on 
the Symantec Web Gateway can ONLY be updated with authorized and tested 
versions distributed by Symantec.

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 


Symantec thanks Brandon Perry working through HP Zero Day Initiative (ZDI) for 
submitting the command injection and SQL injection for SWG 5.2.  Symantec 
further thanks ZDI for working with us as we address them.

Symantec thanks Min1214 of INFOSEC Inc. ( working 
through the Korean CERT, KR-CERT, and for reporting the blind SQL 
injection and the XSS in 5.1.x
