Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
Keyfactor EJBCA 9.3.3 及以下版本在通过注册机构（RA）用户界面自动续期客户端证书时，授权检查不足。这使得已使用有效客户端证书进行身份验证的远程用户，即使终端实体状态和/或配置文件设置本应禁止续期，仍能成功续期其证书。攻击者必须持有有效的 TLS 客户端证书，并且需被授权访问 RA 用户界面（可通过该证书本身，或通过拥有 PublicAccessAuthenticationToken 的角色成员身份实现）。

Vulnerability Description
Keyfactor EJBCA through 9.3.3 performs insufficient authorization checks when self-renewing a client certificate via the RA (Registration Authority) User Interface. This allows a remote user, authenticated with a valid client certificate, to renew their certificate even if the end entity status and/or profile settings should deny renewal. The attacker must have a valid TLS client certificate, and must be authorized to use the RA User Interface, either with the certificate, or via a role membership for PublicAccessAuthenticationToken.
