Information Disclosure
Details
Symantec was notified of several security issues impacting Symantec’s Messaging Gateway management console. Issues the affected versions of Symantec Messaging Gateway may be susceptible to include:
In a normal installation, neither the Symantec Messaging Gateway appliance management interface nor the system hosting the software application would be externally accessible from the network environment nor used to access external web sites. These restrictions reduce exposure to the majority of these issues from external sources. However, an authorized but unprivileged network user or an external attacker able to successfully leverage network access or entice an authorized user to access a malicious URL could attempt to exploit these issues.
Symantec Response
Symantec engineers verified the issues and released an update to address them. Symantec engineers continue to review all functionality to further enhance the overall security of Symantec Messaging Gateway. Symantec strongly recommends Symantec Messaging Gateway customers update to the latest release of Symantec Messaging Gateway 10.x at their earliest opportunity to protect from any attempts to target these types of issues. Symantec knows of no exploitation of or adverse customer impact from this issue.
Symantec Messaging Gateway 10.x is currently available through normal update channels.
