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

Description :

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.
