TITLE

Cisco CallManager Service disruption in (DoS) Vulnerabilities

DESCRIPTION

Cisco CallManager 3.2 and earlier, 3.3 before 3.3(5)SR1, 4.0 before 4.0(2a)SR2c, and 4.1 before 4.1(3)SR2 allow remote attackers to (1) cause a denial of service (CPU and memory consumption) via a large number of open TCP connections to port 2000 and (2) cause a denial of service (fill the Windows Service Manager communication queue) via a large number of TCP connections to port 2001, 2002, or 7727. Cisco CallManager There is a service disruption (DoS) There are vulnerabilities that are put into a state.Service disruption by a third party (DoS) There is a possibility of being put into a state. CallManager is susceptible to multiple remote denial of service vulnerabilities. These issues are documented in Cisco bugs CSCea53907, CSCsa86197, CSCsb16635 and CSCsb64161, which are available to Cisco customers. Attackers may exploit these vulnerabilities to crash the affected service, effectively denying service to legitimate users. Cisco CallManager (CCM) is a set of call processing components based on the Cisco Unified Communications solution of Cisco. Under certain circumstances, CCM will keep the TCP connection open indefinitely until the CCM service is restarted or the server is restarted. Successful exploitation of these vulnerabilities could result in a denial of service attack, causing high CPU usage, interrupting service, or restarting the server, which could then cause the phone to become unresponsive, log off the phone from the CCM, or restart the CCM.
