Cross-site scripting

Description:

Symantec My VIP portal was susceptible to a cross-site scripting (XSS) exploit, which is a type of issue that can enable attackers to inject client-side scripts into web pages viewed by other users or potentially bypass access controls such as the same-origin policy.

 

MITIGATION

 

This issue was validated by the product team engineers. The affected My VIP portal has been patched with a fix. No additional action is required by customers. At this time, Symantec is not aware of any exploitations or adverse customer impact from this issue.

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 for 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.
