A vulnerability in the Web Bridge interface of the Cisco Meeting Server (CMS), formerly Acano Conferencing Server, could allow an authenticated, remote attacker to retrieve memory contents, which could lead to the disclosure of confidential information. In addition, the attacker could potentially cause the application to crash unexpectedly, resulting in a denial of service (DoS) condition. The attacker would need to be authenticated and have a valid session with the Web Bridge.
The vulnerability is due to insufficient input validation of an HTTP request. An attacker could exploit this vulnerability by sending a crafted HTTP packet to a targeted application. A successful exploit could allow the attacker to retrieve memory contents, which could lead to the disclosure of confidential information or cause a DoS condition.
There are no workarounds that address this vulnerability.

This capability exists via collaboration between Cisco and Acano, who joined Cisco in early 2016. Software releases prior to 2.0 are available via Acano's website at https://www.acano.com/support/downloads.
