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's different from CVSS.

VPR Score: 6.5


The remote device is missing a vendor-supplied security patch.


According to its self-reported version number, the remote Junos device uses a predictable IP ID sequence number. It is, therefore, vulnerable to a family of attacks that rely on this property, including a susceptibility to being used as a 'zombie' host in an 'idle scan' blind port scan of another remote host.
