name: VMware NSX Manager XStream Pre-authenticated Remote Code Execution

description: |
|
||
|
|
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.
