Authentication Bypass

MITIGATION

 

A Critical System Protection update, version 8.0 MP1 HF1, has been released which addresses the aforementioned issue. Note that the latest Critical System Protection releases and patches are available to customers through normal support channels. Symantec has also created additional detections and protections which are in place and is continuing to monitor any attempts of this exploit against our products. At this time, there is no evidence of any attempts at this exploit in the wild.

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.
