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).
The vulnerability has a CVSS score of 9.8, classifying it as critical. This high severity indicates the potential for significant impact, including high confidentiality, integrity, and availability impacts. Organizations using VMware Cloud Director should prioritize remediation to prevent unauthorized access and potential data breaches.
Given the exploitability of this vulnerability, organizations must act promptly to mitigate risks associated with this flaw. The urgency for defenders to patch their systems is paramount, as the vulnerability could be leveraged by attackers for unauthorized access.
In light of the critical nature of this vulnerability, it is essential for organizations to ensure they are operating on versions of Photon OS that do not contain the affected sssd version. Organizations should take immediate action to upgrade their systems to mitigate this risk.
