Cisco Unified MeetingPlace Web Conferencing Server contains a vulnerability that could allow an unauthenticated, remote attacker to bypass security restrictions. Updates are not available.
A vulnerability in the web framework of Cisco Unified MeetingPlace Web Conferencing Server could allow an unauthenticated, remote attacker to bypass certain access-control settings which may lead to the disclosure of information due to the attacker accessing restricted pages.
The vulnerability is due to insufficient validation of parameters passed by the endpoint client to the server. An attacker could exploit this vulnerability by modifying requests from the client or crafting malicious HTTP requests and submitting them to the affected system. Successful exploitation could allow the attacker to access certain areas of the web interface that require authorization.
Cisco has confirmed this vulnerability in a security notice; however, software updates are not available.
At the time this alert was first published, Cisco Unified MeetingPlace Web Conferencing versions 8.5 SR2(4) and prior were vulnerable. Subsequent versions of Cisco Unified MeetingPlace Web Conferencing may also be affected.
