VMware Warns of Exploit for Recent NSX-V Vulnerability


An end-of-life (EOL) product installed as a plug-in to VMware vCenter Server, NSX-V is a network virtualization solution offering networking and security functionality, including VPN, logical switching and routing, and more. The product is bundled within VMware Cloud Foundation.

Last week, VMware announced the availability of patches for CVE-2021-39144 (CVSS score of 9.8), an RCE flaw via the open source library XStream, warning that it could allow a remote attacker to execute arbitrary code in the context of ‘root’ on the appliance.

The company also notes that, while it typically does not mention EOL products in advisories, the severity of this bug led to the release of a patch as an exception.
