Symantec Management Console fails to properly validate/sanitize certain external input, allowing the potential for reflected cross-site scripting attempts. These attempts may come from authorized, but non-privileged network users or, in some instances, from unauthorized external individuals who are able to entice an actively logged-in management console user to click on a maliciously-crafted HTML link. Successful targeting of these issues could result in an authorized Symantec Management Console user’s management session with associated privileges being hijacked.


Cross-site scripting is a trust exploitation that requires enticing a previously authenticated user to click on a malicious HTML link. An external attacker would need to successfully entice an authorized, privileged Symantec Management Console user to visit a malicious web site or click on a malicious HTML link in an email in any attempt to take advantage of this issue. In a normal installation, the Symantec Management console should not be accessible external to the network environment.


This issue was validated by the product team engineers. A Symantec Management Console set of updates, version ITMS 8.1 RU1 as well as patches ITMS 8.0_POST_HF6 & ITMS 7.6_POST_HF7, have been released which address the aforementioned vulnerabilities. Note that the Symantec Management Console’s latest release and patches are available to customers through normal support channels. At this time, Symantec is not aware of any exploitations or adverse customer impact from these issues.


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.
