CVE-2023-34060
CWE-306Published: November 14, 2023· Updated: Jun 17, 2026
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).
Risk Analysis
VMware Cloud Director appliances upgraded to version 10.5 contain an authentication bypass vulnerability affecting SSH and management console ports. This flaw allows an attacker with network access to bypass login restrictions and gain unauthorized access. The issue stems from an outdated sssd component in the underlying Photon OS.
No public exploit is known, and the vulnerability is not in the CISA KEV. It is remotely exploitable with low complexity.
Update the underlying Photon OS to a version containing sssd-2.8.1-11 or higher. Ensure that management ports are not exposed to untrusted networks.
Technical Analysis
CVE-2023-34060 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
