CVE-2020-4006, as the flaw is tracked, is a command-injection flaw, meaning it allows attackers to execute commands of their choice on the operating system running the vulnerable software. These vulnerabilities are the result of code that fails to filter unsafe user input such as HTTP headers or cookies. VMware patched CVE-2020-4006 after being tipped off by the NSA.
