Juniper Junos Certificate Validation Bypass (JSA10755)

medium Nessus Plugin ID 92513
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


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.
