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 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 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.
