Vulnerability Description

A vulnerability in the role-based resource checking functionality of the Cisco Unified Computing System (UCS) Director could allow an authenticated, remote attacker to view unauthorized information for any virtual machine in the UCS Director end-user portal and perform any permitted operations on any virtual machine. The permitted operations can be configured for the end user on the virtual machines with either of the following settings: The virtual machine is associated to a Virtual Data Center (VDC) that has an end user self-service policy attached to the VDC. The end user role has VM Management Actions settings configured under User Permissions. This is a global configuration, so all the virtual machines visible in the end-user portal will have the VM management actions available. The vulnerability is due to improper user authentication checks. An attacker could exploit this vulnerability by logging in to the UCS Director with a modified username and valid password. A successful exploit could allow the attacker to gain visibility into and perform actions against all virtual machines in the UCS Director end-user portal of the affected system. This vulnerability affects Cisco Unified Computing System (UCS) Director releases 6.0 and 6.5 prior to patch 3 that are in a default configuration. Cisco Bug IDs: CSCvh53501.
