CVE-2018-0139: A vulnerability in the Interactive Voice Response (IVR) management connection interface for Cisco Unified C...

A vulnerability in the Interactive Voice Response (IVR) management connection interface for Cisco Unified Customer Voice Portal (CVP) could allow an unauthenticated, remote attacker to cause the IVR connection to disconnect, creating a system-wide denial of service (DoS) condition. The vulnerability is due to improper handling of a TCP connection request when the IVR connection is already established. An attacker could exploit this vulnerability by initiating a crafted connection to the IP address of the targeted CVP device. An exploit could allow the attacker to disconnect the IVR to CVP connection, creating a DoS condition that prevents the CVP from accepting new, incoming calls while the IVR automatically attempts to re-establish the connection to the CVP. This vulnerability affects Cisco Unified Customer Voice Portal (CVP) Software Release 11.5(1). Cisco Bug IDs: CSCve70560.

Security readout for executives and security teams

This CVE can let a remote unauthenticated attacker disrupt Cisco Unified CVP call handling by forcing the IVR-to-CVP connection to drop. In affected environments, the platform may stop accepting new incoming calls until the IVR reconnects. Exposure is most relevant to organizations running Cisco Unified Customer Voice Portal Software Release 11.5(1), especially if the CVP device IP is reachable by untrusted networks. Treat this as a business continuity risk for contact center operations. Prioritize if CVP supports customer-facing call intake or emergency workflows. Mitigation focus: Confirm whether Cisco Unified CVP 11.5(1) is deployed.; Review Cisco advisory cisco-sa-20180221-cvp for vendor fixes or workarounds.; Restrict access to CVP and IVR management interfaces to trusted networks..
