Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Improper Authentication
EUVDB-ID: #VU77208
Risk: High
CVSSv4.0: 8.4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Amber]
CVE-ID: CVE-2023-20867
CWE-ID:
CWE-287 - Improper Authentication
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to an error in the vgauth module. An attacker who compromised the ESXi host can bypass authentication process and execute privileged commands across Windows, Linux, and PhotonOS (vCenter) guest VMs without authentication of guest credentials from a compromised ESXi host and no default logging on guest VMs.
Note, the vulnerability is being actively exploited in the wild by the UNC3886 APT actor.
Update the affected package open-vm-tools to the latest version.

2) Cryptographic issues
EUVDB-ID: #VU80188
Risk: Medium
CVSSv4.0: 4.9 [CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2023-20900
CWE-ID:
CWE-310 - Cryptographic Issues
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to improper verification of SAML token signature. A remote attacker can bypass SAML token signature verification and perform man-in-the-middle (MITM) network positioning between vCenter server and the virtual machine.
MitigationUpdate the affected package open-vm-tools to the latest version.
