Vulnerability Title
Junos OS: An invalid certificate causes a Denial of Service in the Internet Key Exchange (IKE) process
Source: CVE Program / CVE List V5
Vulnerability Description
An Improper Check for Unusual or Exceptional Conditions vulnerability in the the Public Key Infrastructure daemon (pkid) of Juniper Networks Junos OS allows an unauthenticated networked attacker to cause Denial of Service (DoS).
The pkid is responsible for the certificate verification. Upon a failed verification, the pkid uses all CPU resources and becomes unresponsive to future verification attempts. This means that all subsequent VPN negotiations depending on certificate verification will fail.
This CPU utilization of pkid can be checked using this command:
root@srx> show system processes extensive | match pkid
xxxxx root 103 0 846M 136M CPU1 1 569:00 100.00% pkid
