1) Improper Certificate Validation (CVE-ID: CVE-2022-40617)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an error within the revocation plugin, which uses potentially untrusted OCSP URIs and
CRL distribution points (CDP) in certificates. A remote attacker can initiate the IKE_SAs and send crafted certificates that contain URIs
pointing to servers under their control. As a result, a remote attacker can perform a denial of service (DoS) attack.
