CVSS2 Base Score: 5.82
Impact 6.44, Exploitability 6.45
CVSS2 Vector: AV:A/AC:L/Au:N/C:P/I:P/A:P
Exploit Publicly Available: No
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 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 18.104.22.1686 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 22.214.171.1246 (or later)
If the Current Version is less than 126.96.36.1996, update to the latest available version
Symantec is not aware of any exploitation of, or adverse customer impact from this issue.
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.
