Symantec was notified of a cross-site scripting issue present in the Symantec IM Manager console. The console fails to properly filter/ validate external input from non-privileged users with authorized access to the console. This could result in unauthorized access to other users’ session cookies or to unauthorized network information.
Symantec product engineers have verified the issue and released a fix for affected product versions. Symantec recommends all customers apply the latest available update to protect against threats of this nature.
Symantec is not aware of any exploitation of or adverse customer impact from this issue.
Symantec recommends all customers apply the fix, Symantec IM Manager 8.4.13, available through the FileConnect -Electronic Software Distribution web site.
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.
Run under the principle of least privilege where possible to limit the impact of exploit by threats.
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
