Workaround

Before upgrading to NDLP 9.3.4.1, McAfee strongly recommends that you configure system and network access controls to the below best practices:
  • Change the default root password of the system to a strong, un-guessable password.
  • Place the NDLP Management console only on a trusted network. 
  • Only give accounts on NDLP systems to personnel with a "need-to-know".
  • Place network restrictions such that only NDLP Monitors can communicate with NDLP Managers.
  • Only use a single network interface card (NIC) for inter-system communications.
  • Present management functions only on a single NIC. Configure the management NIC to accept connections only from a trusted, restricted network.

What is CVSS?
CVSS, or Common Vulnerability Scoring System, is the result of the National Infrastructure Advisory Council’s effort to standardize a system of assessing the criticality of a vulnerability. This system offers an unbiased criticality score between 0 and 10 that customers can use to judge how critical a vulnerability is and plan accordingly. For more information, please visit the CVSS website at: http://www.first.org/cvss/.

When calculating CVSS scores, McAfee has adopted a philosophy that fosters consistency and repeatability. Our guiding principle for CVSS scoring is to score the exploit under consideration by itself. We consider only the immediate and direct impact of the exploit under consideration. We do not factor into a score any potential follow-on exploits that might be made possible by successful exploitation of the issue being scored
