Overview
Symantecs Web Gateway management GUI is susceptible to a blind SQL injection
attack which could result in injection of arbitrary code into the backend
database.
Product(s) Affected
Product Version Solution
Symantec Web Gateway 4.5 Apply DB update 4.5.0.376
Details
Symantec was notified of a blind SQL injection vulnerability in the GUI
management console of the Symantec Web Gateway Appliance. The interface fails
to properly filter/validate external input.
In a normal installation, the affected management interface should not be
accessible external to the network. However, an authorized but unprivileged
network user or an external attacker who can leverage network access could
attempt an attack against the management interface. The success exploitation of
this vulnerability could potentially result in arbitrary code injection into
and possible compromise of the appliance backend database.
Symantec Response
Symantec engineers have verified this issue and released an update to address
it. Symantec engineers did additional reviews of related functionality to
further enhance the overall security of Symantec Web Gateway. This issue is
resolved in data base update 4.5.0.376 which is currently available to
customers. Symantec recommends all customers ensure the latest available
updates are installed to protect against threats of this nature.
Customers should ensure the update is on their system as follows:
* Log in to the Symantec Web Gateway user interface
* Navigate to Administration->updates
* Ensure that the Current Version is listed as 4.5.0.376 (or later)
* If the Current Version is less than 4.5.0.376, update to the latest
available version
Symantec is not aware of any exploitation of, or adverse customer impact from
this issue.
Best Practices
As part of normal best practices, Symantec strongly recommends:
* Restrict access to administration or management systems to privileged
users.
* Disable remote access or restrict it to trusted/authorized systems 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 vulnerabilities.
