A vulnerability in an API of the Web Bridge feature of Cisco Meeting Server could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. This vulnerability is due to insufficient validation of HTTP requests. An attacker could exploit this vulnerability by sending crafted HTTP packets to an affected device. A successful exploit could allow the attacker to cause a partial availability condition, which could cause ongoing video calls to be dropped due to the invalid packets reaching the Web Bridge.

A vulnerability in an API of the Call Bridge feature of Cisco Meeting Server could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. This vulnerability is due to improper handling of large series of message requests. An attacker could exploit this vulnerability by sending a series of messages to the vulnerable API. A successful exploit could allow the attacker to cause the affected device to reload, dropping all ongoing calls and resulting in a DoS condition.

A vulnerability in the Extensible Messaging and Presence Protocol (XMPP) feature of Cisco Meeting Server software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition for users of XMPP conferencing applications. Other applications and processes are unaffected. The vulnerability is due to improper input validation of XMPP packets. An attacker could exploit this vulnerability by sending crafted XMPP packets to an affected device. An exploit could allow the attacker to cause process crashes and a DoS condition for XMPP conferencing applications.

A vulnerability in the CLI configuration shell of Cisco Meeting Server could allow an authenticated, local attacker to inject arbitrary commands as the root user. The vulnerability is due to insufficient input validation during the execution of a vulnerable CLI command. An attacker with administrator-level credentials could exploit this vulnerability by injecting crafted arguments during command execution. A successful exploit could allow the attacker to perform arbitrary code execution as root on an affected product.

A vulnerability in the web-based management interface of Cisco Meeting Server could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack and perform arbitrary actions on an affected device. The vulnerability is due to insufficient CSRF protections for the web-based management interface of an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to follow a customized link. A successful exploit could allow the attacker to perform arbitrary actions on an affected device by using a web browser and with the privileges of the user.

A vulnerability in Cisco Meeting Server (CMS) could allow an unauthenticated, adjacent attacker to access services running on internal device interfaces of an affected system. The vulnerability is due to incorrect default configuration of the device, which can expose internal interfaces and ports on the external interface of the system. A successful exploit could allow the attacker to gain unauthenticated access to configuration and database files and sensitive meeting information on an affected system. This vulnerability affects Cisco Meeting Server (CMS) 2000 Platforms that are running a CMS Software release prior to Release 2.2.13 or Release 2.3.4. Cisco Bug IDs: CSCvg76471.

A vulnerability in Cisco Meeting Server versions prior to 2.2.2 could allow an authenticated, remote attacker to cause the system to reload, resulting in a denial of service (DoS) condition. The vulnerability is due to video calls being made on systems with a particular configuration. An attacker could exploit this by knowing a valid URI that directs to a Cisco Meeting Server. An attacker could then make a video call and cause the system to reload. Cisco Bug IDs: CSCve65931.

A vulnerability in the H.264 decoder function of Cisco Meeting Server could allow an unauthenticated, remote attacker to cause a Cisco Meeting Server media process to restart unexpectedly when it receives an illegal H.264 frame. The vulnerability is triggered by an H.264 frame that has an invalid picture parameter set (PPS) value. An attacker could exploit this vulnerability by sending a malformed H.264 frame to the targeted device. An exploit could allow the attacker to cause a denial of service (DoS) condition because the media process could restart. The media session should be re-established within a few seconds, during which there could be a brief interruption in service. Cisco Bug IDs: CSCvg12559.

A vulnerability in the Traversal Using Relay NAT (TURN) server included with Cisco Meeting Server (CMS) could allow an authenticated, remote attacker to gain unauthenticated or unauthorized access to components of or sensitive information in an affected system. The vulnerability is due to an incorrect default configuration of the TURN server, which could expose internal interfaces and ports on the external interface of an affected system. An attacker could exploit this vulnerability by using a TURN server to perform an unauthorized connection to a Call Bridge, a Web Bridge, or a database cluster in an affected system, depending on the deployment model and CMS services in use. A successful exploit could allow the attacker to gain unauthenticated access to a Call Bridge or database cluster in an affected system or gain unauthorized access to sensitive meeting information in an affected system. To exploit this vulnerability, the attacker must have valid credentials for the TURN server of the affected system. This vulnerability affects Cisco Meeting Server (CMS) deployments that are running a CMS Software release prior to Release 2.0.16, 2.1.11, or 2.2.6. Cisco Bug IDs: CSCvf51127.

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.
