VMware fixes critical RCE in VMware Cloud Foundation
VMware addressed a critical remote code execution vulnerability in VMware Cloud Foundation tracked as CVE-2021-39144.
VMware has released security updates to address a critical vulnerability, tracked as CVE-2021-39144 (CVSSv3 9.8), in VMware Cloud Foundation. VMware Cloud Foundation
is the industry’s most advanced hybrid cloud platform. It provides a complete set of software-defined services for compute, storage, networking, security and cloud management to run enterprise apps—traditional or containerized —in private or public environments.
The remote code execution vulnerability resides in the XStream open-source library. Unauthenticated attackers can exploit the vulnerability in low-complexity attacks without user interaction.
“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.” reads the advisory published by the company.
The product team has also released patches for end-of-life products due to the severity of the vulnerability.
The virtualization giant also addressed an XML External Entity (XXE) vulnerability tracked as CVE-2022-31678 (CVSSv3 5.3.). An unauthenticated user may exploit this issue to cause a denial-of-service condition or unintended information disclosure.
Both flaws were reported by researchers Sina Kheirkhah and Steven Seeley from Source Incite.
VMware also published separate guidance to upgrade NSX-V 6.4.14 appliances on VMware Cloud Foundation 3.x.
Below is the step-by-step workaround procedure:
Step 1: Perform below steps on each VMware NSX-V instance deployed in your VMware Cloud Foundation environment
- Apply the NSX-v 6.4.14 patch available at the Product Patch page to all NSX-V instances (Management & VI Domain) in the environment.
Step 2: Perform below steps on each SDDC Manager VM deployed in your Cloud Foundation environment
- Login to SDDC manager Virtual Machine via SSH and sudo to root account
- Verify the NSX-V version on the inventory
- API to update NSX-v hot patch version: 6.4.14-20609341
- Verify the NSX-V Version
