This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of VMware ESXi. Authentication is not required to exploit this vulnerability. The specific flaw exists within the processing of SLP messages. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the SLP daemon.
