VMware vCenter and ESX Multiple Vulnerabilities

Date Disclosed:

Date Patched:

Affected Software:

VMware vCenter 4.1
VMware ESX 4.1

VMware vCenter and ESX contain multiple vulnerabilities, including a failure to properly verify login credentials in Active Directory with anonymous LDAP binding (vCenter only) and a vulnerable version of Java (vCenter and ESX). Successful exploitation of these vulnerabilities may lead to information disclosure, denial of service, or remote code execution.

Exploitation of these vulnerabilities is possible via multiple different vectors. Attackers who successfully exploit these vulnerabilities will be able to execute code on the vulnerable system, possibly allowing the attacker full control of the target system.
