New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it is different from CVSS.

VPR Score: 5.2


The remote host has a predictable TCP sequence number generator.


According to the version of one or more Juniper NSM servers running on the remote host, it is potentially vulnerable to denial of service and network session hijacking attacks due to a weak IP sequence number generator.


Upgrade to NSM version 2011.4s3 / 2012.1 or higher.
