A vulnerability in the CLI command-parsing code of Cisco Meeting Server could allow an authenticated, local attacker to perform command injection and escalate their privileges to root. The attacker must first authenticate to the application with valid administrator credentials. The vulnerability is due to insufficient validation of user-supplied input at the CLI for certain commands. An attacker could exploit this vulnerability by authenticating to the affected application and submitting a crafted CLI command for execution at the Cisco Meeting Server CLI. An exploit could allow the attacker to perform command injection and escalate their privilege level to root. Vulnerable Products: This vulnerability exists in Cisco Meeting Server software versions prior to and including 2.0, 2.1, and 2.2. Cisco Bug IDs: CSCvf53830.

An HTTP Packet Processing 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. Affected Products: This vulnerability affects Cisco Meeting Server software releases prior to 2.1.2. This product was previously known as Acano Conferencing Server. More Information: CSCvc89551. Known Affected Releases: 2.0 2.0.7 2.1. Known Fixed Releases: 2.1.2.

A vulnerability in the Session Description Protocol (SDP) parser of Cisco Meeting Server could allow an unauthenticated, remote attacker to execute arbitrary code on an affected system. This vulnerability affects the following products: Cisco Meeting Server releases prior to Release 2.0.3, Acano Server releases 1.9.x prior to Release 1.9.5, Acano Server releases 1.8.x prior to Release 1.8.17. More Information: CSCva76004. Known Affected Releases: 1.8.x 1.92.0.

A vulnerability in the Extensible Messaging and Presence Protocol (XMPP) service of the Cisco Meeting Server (CMS) before 2.0.6 and Acano Server before 1.8.18 and 1.9.x before 1.9.6 could allow an unauthenticated, remote attacker to masquerade as a legitimate user. This vulnerability is due to the XMPP service incorrectly processing a deprecated authentication scheme. A successful exploit could allow an attacker to access the system as another user.

A vulnerability in Cisco Meeting Server could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack against a Web Bridge user. More Information: CSCvb03308. Known Affected Releases: 1.8, 1.9, 2.0.

A vulnerability in Web Bridge for Cisco Meeting Server could allow an unauthenticated, remote attacker to retrieve memory from a connected server. More Information: CSCvb03308. Known Affected Releases: 1.8, 1.9, 2.0.
