VMware vCenter Server is prone to a remote vulnerability that allows attackers to take advantage of an insecure deployment of the JMX/RMI service used to manage and monitor the Java Virtual Machine. By exploiting known methods, it is possible to remotely load an MLet file from an attacker controlled web server that points at a jar file.
The vulnerability is due to an error while parsing crafted PRX files which can result in an buffer overflow. This module runs a malicious web site on the Core Impact Console and waits for an unsuspecting user to trigger the exploit by connecting to the web site.
