Symantec's Web Gateway (SWG) Appliance management console is susceptible to
operating system command injection by an authenticated but less-privileged
Product Version Solution
Symantec Web Gateway Appliance 5.2.1 and prior Symantec Web Gateway 5.2.2
NOTE: Customers should always ensure they are running the latest updates
Symantec was notified of an OS command injection vulnerability in PHP script
which impacts the SWG management console. The results of successful
exploitation could potentially range from unauthorized disclosure of sensitive
data to possible unauthorized access to the Symantec Web Gateway Appliance.
Unauthenticated arbitrary commands can potentially be injected into existing
application scripts accessible though the SWG consoles interface if the
attacker already has some level of privileged access. This issue is of limited
scope and impact and has been addressed in SWG 5.2.2.
In a normal installation, the Symantec Web Gateway management interface should
not be externally accessible from the network environment and would require
access to the network either by an authorized network user or an external
attacker able to leverage network access.
Symantec engineers have verified these issues and have addressed them in SWG
5.2.2. Symantec continues to review related functionality in order to further
enhance the overall security of the Symantec Web Gateway product.
Symantec has released Symantec Web Gateway 5.2.2, currently available to
customers through normal support locations. Customers should ensure they are
on this latest release. To confirm customers are running the latest updates,
check the "Current Software Version -> Current Version" on the Administration
- -> Updates page. Alternatively, customers can click the "Check for Updates"
button on the Administration -> Updates page to verify that they are running
the latest software version.
Symantec will be releasing the following IPS signature:
* Attack: Symantec Web Gateway Command Injection Vulnerability
These detections will be available through normal Symantec security update
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
* 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 Egidio Romano, Secunia Research for reporting this issue and
for providing full coordination while it was resolved by Symantec.
