An attacker could exploit this vulnerability by sending a malformed SIP packet to an affected Cisco Unified Communications Manager or Unified Communications Manager Session Management Edition. A successful exploit could allow the attacker to trigger a new registration process on all connected phones, temporarily disrupting service.\r\n\r\nCisco has released software updates that address this vulnerability.

Customers may only install and expect support for software versions and feature sets for which they have purchased a license. By installing, downloading, accessing, or otherwise using such software upgrades, customers agree to follow the terms of the Cisco software license:\r\nhttps://www.cisco.com/c/en/us/products/end-user-license-agreement.html [\"https://www.cisco.com/c/en/us/products/end-user-license-agreement.html\"]\r\n\r\nAdditionally, customers may only download software for which they have a valid license, procured from Cisco directly, or through a Cisco authorized reseller or partner. In most cases this will be a maintenance upgrade to software that was previously purchased. Free security software updates do not entitle customers to a new software license, additional software feature sets, or major revision upgrades.\r\n\r\nWhen considering software upgrades, customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories and Alerts page [\"https://www.cisco.com/go/psirt\"], to determine exposure and a complete upgrade solution.\r\n\r\nIn all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers.\r\n\r\nCustomers Without Service Contracts\r\n\r\nCustomers who purchase directly from Cisco but do not hold a Cisco service contract and customers who make purchases through third-party vendors but are unsuccessful in obtaining fixed software through their point of sale should obtain upgrades by contacting the Cisco TAC:\r\nhttps://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html [\"https://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html\"]\r\n\r\nCustomers should have the product serial number available and be prepared to provide the URL of this advisory as evidence of entitlement to a free upgrade.\r\n\r\nFixed Releases\r\n\r\nCustomers are advised to upgrade to an appropriate fixed software release or apply the corresponding patch file as indicated in the following table:\r\n                                Cisco Unified Communications Manager Major Release              Fix Options                                              Prior to 10.5(2)              Migrate to 10.5(2) and apply patch file ciscocm.V10-5-2-SU7-SU8_CSCvo70834_C0003-1.cop.sgn [\"https://software.cisco.com/download/home/285963825/type/282204704/release/COP-Files\"]                                  10.5(2)              Apply patch file ciscocm.V10-5-2-SU7-SU8_CSCvo70834_C0003-1.cop.sgn [\"https://software.cisco.com/download/home/285963825/type/282204704/release/COP-Files\"]                                  11.5              Apply patch file ciscocm.V11-5-1-SU5-SU6_CSCvo70834_C0003-1.cop.sgn [\"https://software.cisco.com/download/home/286306100/type/282204704/release/COP-Files\"]                                  12.0              Apply patch file ciscocm.V12-0-1-22900-11_CSCvo70834_C0003-1.cop.sgn [\"https://software.cisco.com/download/home/286313357/type/286319173/release/COP-Files\"] or upgrade to 12.0(1)SU3                                  12.5              Apply patch file ciscocm.V12-5-1-10000-22_CSCvo70834_C0003-1.cop.sgn [\"https://software.cisco.com/download/home/286322286/type/286319173/release/COP-Files\"] or upgrade to 12.5(1)SU1\r\nThe patch files are available in the Cisco Unity Connection Utilities - COP-Files section of the software downloads page for each release.
