|            |Symantec VIP Enterprise Gateway may be susceptible to a         |
|            |cross-site scripting (XSS) exploit, which is a type of issue    |
|Description:|that can enable attackers to inject client-side scripts into web|
|            |pages viewed by other users. A cross-site scripting             |
|            |vulnerability may be used by attackers to potentially bypass    |
|            |access controls such as the same-origin policy.                 |

Mitigation

This issue was validated by the product team engineers. A Symantec VIP
Enterprise Gateway f ix has been provided for EGversions 9.8.4 and 9.7.1.
Reference the following link for installation details: https://
support.symantec.com/en_US/article.TECH253787.html .

Note that the latest Symantec VIP Enterprise Gateway 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 this issue.

Symantec recommends the following measures to reduce risk of attack:

  o Restrict access to administrative or management systems to authorized
    privileged users.
  o Restrict remote access to trusted/authorized systems only.
  o Run under the principle of least privilege, where possible, to limit the
    impact of potential exploit.
  o Keep all operating systems and applications current with vendor patches.
  o 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.
  o 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.
