After security researchers have developed and published proof-of-concept exploit code targeting a critical vCenter remote code execution vulnerability, attackers are now actively scanning for vulnerable Internet-exposed VMware servers. We've detected mass scanning activity targeting vulnerable VMware vCenter servers.
Just one day after VMware announced the availability of patches for a critical vulnerability affecting vCenter Server, hackers have started scanning the internet for vulnerable servers. The flaw, tracked as CVE-2021-21972, affects the vSphere Client component of vCenter Server and it can be exploited by a remote, unauthenticated attacker to execute arbitrary commands with elevated privileges on the operating system that hosts vCenter Server.
