VMware ESXi SLP Use-After-Free Privilege Escalation Vulnerability

Lucas Leong (@_wmliang_) of Trend Micro's Zero Day Initiative

0.356 Low




This vulnerability allows local attackers to escalate privileges on affected installations of VMware ESXi. An attacker must first obtain the ability to execute low-privileged code on the target system in order 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 escalate privileges and execute arbitrary code in the context of root.
