Detailsinfo

A vulnerability was found in VMware Photon OS 1.0 on Linux. It has been rated as very critical. This issue affects an unknown part of the component SSH Public Key. The manipulation with an unknown input leads to a hard-coded credentials vulnerability. Using CWE to declare the problem leads to CWE-798. The product contains hard-coded credentials, such as a password or cryptographic key, which it uses for its own inbound authentication, outbound communication to external components, or encryption of internal data. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

VMware Photos OS OVA 1.0 before 2016-08-14 has a default SSH public key in an authorized_keys file, which allows remote attackers to obtain SSH access by leveraging knowledge of the private key.

The weakness was disclosed 08/15/2016 as VMSA-2016-0012 as confirmed security advisory (Website). The advisory is shared at vmware.com. The identification of this vulnerability is CVE-2016-5333 since 06/07/2016. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 03/27/2019). MITRE ATT&CK project uses the attack technique T1110.001 for this issue. The advisory points out:

A public ssh key used in the Photon OS build environment was inadvertently left in the original Photon OS 1.0 OVAs. This issue would have allowed anyone with the corresponding private key to access any Photon OS system built from the original 1.0 OVAs.

Applying a patch is able to eliminate this problem. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at SecurityFocus (BID 92474†) and SecurityTracker (ID 1036628†). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
