List of CVEs: CVE-2021-39144
VMware Cloud Foundation (NSX-V) contains a remote code execution vulnerability via XStream open source library. VMware has evaluated the severity of this issue to be in the Critical severity range with a maximum CVSSv3 base score of 9.8. Due to an unauthenticated endpoint that leverages XStream for input serialization in VMware Cloud Foundation (NSX-V), a malicious actor can get remote code execution in the context of 'root' on the appliance. VMware Cloud Foundation 3.x and more specific NSX Manager Data Center for vSphere up to and including version 6.4.13 are vulnerable to Remote Command Injection. This module exploits the vulnerability to upload and execute payloads gaining root privileges.
Module Ranking and Traits
Module Ranking:
- excellent: The exploit will never crash the service. This is the case for SQL Injection, CMD execution, RFI, LFI, etc. No typical memory corruption exploits should be given this ranking unless there are extraordinary circumstances. More information about ranking can be found here.
Reliability:
- repeatable-session: The module is expected to get a shell every time it runs.
Stability:
- crash-safe: Module should not crash the service.
Side Effects:
- ioc-in-logs: Module leaves signs of a compromise in a log file (Example: SQL injection data found in HTTP log).
- artifacts-on-disk: Modules leaves a payload or a dropper on the target machine.

Knowledge Base
Vulnerable Application
VMware Cloud Foundation contains a remote code execution vulnerability via XStream open source library CVE-2022-39144.
VMware has evaluated the severity of this issue to be in the Critical severity range with a maximum CVSSv3 base score of 9.8.
Due to an unauthenticated endpoint that leverages XStream for input serialization in VMware Cloud Foundation (NSX-V),
a malicious actor can get remote code execution in the context of root on the appliance.
VMware Cloud Foundation 3.x and more specific NSX Manager Data Center for vSphere up to and including version 6.4.13
are vulnerable to Remote Command Injection.
This module has been tested against VMware NSX Manager (NSX-V) with the specifications listed below:
- VMware NSX Manager
- Version
6.4.13 - Version
6.4.4
Verification Steps
Follow these instructions to install a vulnerable VMware NSX Manager on VirtualBox.
* Go to Download VMware NSX for vSphere 6.4.13
* Note: You need to be a customer with valid VMware subscriptions
* Download the ova file VMware-NSX-Manager-6.4.13-19307994.ova
* Open VirtualBox and import the ova file
* After sucessful import, start the VM and you have a VMware NSX Manager running which is accessible using url https://<nsx-manager-ip>
* Credentials to login: user: admin, password: default
* Use the module and options below to test the vulnerability...

Limitations
The vulnerability check is limited in detecting that VMWare NSX Manager (NSX-V) is running without obtaining the version information.
However all VMware NSX Manager versions up to 6.4.13 are vulnerable, except for 6.4.14, so most detected targets are likely
to be vulnerable.
