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: 2.5


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


According to its self-reported version number, the remote Juniper Junos device is affected by a security bypass vulnerability due to improper validation of self-signed certificates used for IKE and IPsec. An unauthenticated, remote attacker can exploit this, via a specially crafted self-signed certificate, to bypass certificate validation and intercept network traffic.


Upgrade to the relevant Junos software release referenced in Juniper advisory JSA10755. Alternatively, configure all PKI-VPN tunnels to accept only Distinguished Name (DN) as the remote peer's IKE ID.
