Symantec has addressed a directory traversal issue in Symantec Messaging Gateway caused by insufficient sanitization of user-supplied input. This issue could allow unauthorized access to files or directories.
A charting component in the Symantec Messaging Gateway control center does not properly sanitize user input submitted for charting requests. This could potentially result in an authorized but less privileged user gaining access to paths outside the authorized directory. This could potentially provide read access to some files/directories on the server for which the user is not authorized.
The listening port for Symantec Messaging Gateway Control Center should not be accessible outside of the authorized network. Restrict access to the Symantec Messaging Gateway Center to network-authorized, control center privileged users only.
Symantec recommends the following measures to reduce risk of attack:
Restrict access to administrative or management systems to authorized privileged users.
Restrict remote access to trusted/authorized systems only.
Run under the principle of least privilege, where possible, to limit the impact of potential exploit.
Keep all operating systems and applications current with vendor patches.
Follow a multi-layered approach to security. At a minimum, run both firewall and anti-malware applications 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 the detection of attacks or malicious activity related to the exploitation of latent vulnerabilities.
