Official description
VMware Cloud Director Appliance contains an authentication bypass vulnerability in case VMware Cloud Director Appliance was upgraded to 10.5 from an older version. On an upgraded version of VMware Cloud Director Appliance 10.5, a malicious actor with network access to the appliance can bypass login restrictions when authenticating on port 22 (ssh) or port 5480 (appliance management console) . This bypass is not present on port 443 (VCD provider and tenant login). On a new installation of VMware Cloud Director Appliance 10.5, the bypass is not present. VMware Cloud Director Appliance is impacted since it uses an affected version of sssd from the underlying Photon OS. The sssd issue is no longer present in versions of Photon OS that ship with sssd-2.8.1-11 or higher (Photon OS 3) or sssd-2.8.2-9 or higher (Photon OS 4 and 5).
