Title:	Cisco IOS XE Software Cluster Management Protocol Remote Code Execution Vulnerability
Summary:	A vulnerability in the Cisco Cluster Management Protocol (CMP) processing;code in Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a reload of an;affected device or remotely execute code with elevated privileges.
Description:	Summary: A vulnerability in the Cisco Cluster Management Protocol (CMP) processing code in Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a reload of an affected device or remotely execute code with elevated privileges. Vulnerability Insight: The Cluster Management Protocol utilizes Telnet internally as a signaling and command protocol between cluster members. The vulnerability is due to the combination of two factors: - The failure to restrict the use of CMP-specific Telnet options only to internal, local communications between cluster members and instead accept and process such options over any Telnet connection to an affected device, and - The incorrect processing of malformed CMP-specific Telnet options. An attacker could exploit this vulnerability by sending malformed CMP-specific Telnet options while establishing a Telnet session with an affected Cisco device configured to accept Telnet connections. Vulnerability Impact: An exploit could allow an attacker to execute arbitrary code and obtain full control of the device or cause a reload of the affected device. Solution: See the referenced vendor advisory for a solution. CVSS Score: 10.0 CVSS Vector: AV:N/AC:L/Au:N/C:C/I:C/A:C
