Details
SIP is a popular signaling protocol used to manage voice and video calls across IP networks such as the Internet. SIP is responsible for handling all aspects of call setup and termination. Voice and video are the most popular types of sessions that SIP handles, but the protocol is flexible to accommodate for other applications that require call setup and termination. SIP call signaling can use UDP (port 5060), TCP (port 5060), or Transport Layer Security (TLS; TCP port 5061) as the underlying transport protocol.
MGCP is the protocol for controlling telephony gateways from external call control elements known as media gateway controllers or call agents. A telephony gateway is a network element that provides conversion between the audio signals carried on telephone circuits and data packets carried over the Internet or other packet networks.
Multiple DoS vulnerabilities exist in the Cisco PGW 2200 Softswitch SIP implementation, and one vulnerability is in the MGCP implementation.
The following vulnerabilities can cause affected devices to crash:
- CSCsl39126 (registered customers only), CVE ID CVE-2010-0601
- CSCsk32606 (registered customers only), CVE ID CVE-2010-0602
- CSCsk40030 (registered customers only), CVE ID CVE-2010-0603
- CSCsk38165 (registered customers only), CVE ID CVE-2010-0604

- CSCsk04588 (registered customers only), CVE ID CVE-2010-1563
- CSCsz13590 (registered customers only), CVE ID CVE-2010-1567
The following vulnerability may cause an affected device to be unable to accept or create a new TCP connection. Existing calls will not be terminated, but no new SIP connections will be established. If exploited, this vulnerability will also prevent the device from establishing any new HTTP, SSH or Telnet sessions.
- CSCsk13561 (registered customers only), CVE ID CVE-2010-1565
Vulnerability Scoring Details
Cisco has provided scores for the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this security advisory is done in accordance with CVSS version 2.0.
CVSS is a standards-based scoring method that conveys vulnerability severity and helps determine urgency and priority of response.
Cisco has provided a base and temporal score. Customers can then compute environmental scores to assist in determining the impact of the vulnerability in individual networks.
Cisco has provided an FAQ to answer additional questions regarding CVSS at
http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html
Cisco has also provided a CVSS calculator to help compute the environmental impact for individual networks at

Impact
Successful exploitation of all but one vulnerability in this advisory can crash the affected device. The remaining vulnerability will not crash the affected device, but it can lead to a DoS condition in which no new TCP-based connections will be accepted or created.
Software Versions and Fixes
When considering software upgrades, also consult http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution.
In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco Technical Assistance Center (TAC) or your contracted maintenance provider for assistance.
All vulnerabilities listed in this Security Advisory are addressed in Cisco PGW 2200 Softswitch version 9.7(3)S11, version 9.8(1)S5, and subsequent, software releases.
Workarounds
There are no workarounds for the vulnerabilities in this advisory.
In the case of the vulnerability that corresponds to Cisco Bug ID CSCsk13561, administrator must manually reboot the affected device to restore the device's ability to accept new connections. Because vulnerability prevents new TCP-based session to be created, this reboot can be initiated only from the console. If a failover device is configured, existing sessions will continue while the affected device is reloading. Without a failover device, all active sessions will be terminated while the affected device is reloading.
Additional mitigation techniques that can be deployed on Cisco devices within the network are available in the Cisco Applied Mitigation Bulletin companion document for this advisory: http://www.cisco.com/warp/public/707/cisco-amb-20100512-pgw.shtml

SIP is responsible for\nhandling all aspects of call setup and termination. Voice and video\nare the most popular types of sessions that SIP handles, but the\nprotocol is flexible to accommodate for other applications that\nrequire call setup and termination. SIP call signaling can use UDP\n(port 5060), TCP (port 5060), or Transport Layer Security (TLS; TCP\nport 5061) as the underlying transport protocol. \n\nMGCP is the protocol for controlling telephony gateways from external\ncall control elements known as media gateway controllers or call\nagents. A telephony gateway is a network element that provides\nconversion between the audio signals carried on telephone circuits\nand data packets carried over the Internet or other packet networks. \n\nMultiple DoS vulnerabilities exist in the Cisco PGW 2200 Softswitch\nSIP implementation, and one vulnerability is in the MGCP\nimplementation. \n\nThe following vulnerabilities can cause affected devices to crash:\n\n * CSCsl39126 (registered customers only), CVE ID CVE-2010-0601\n * CSCsk32606 (registered customers only), CVE ID CVE-2010-0602\n * CSCsk40030 (registered customers only), CVE ID CVE-2010-0603\n * CSCsk38165 (registered customers only), CVE ID CVE-2010-0604\n * CSCsk44115 (registered customers only), CVE ID CVE-2010-1561\n * CSCsj98521 (registered customers only), CVE ID CVE-2010-1562\n * CSCsk04588 (registered customers only), CVE ID CVE-2010-1563\n * CSCsz13590 (registered customers only), CVE ID CVE-2010-1567\n\nThe following vulnerability may cause an affected device to be unable\nto accept or create a new TCP connection. Existing calls will not be\nterminated, but no new SIP connections will be established. If\nexploited, this vulnerability will also prevent the device from\nestablishing any new HTTP, SSH or Telnet sessions. \n\n * CSCsk13561 (registered customers only), CVE ID CVE-2010-1565\n\nVulnerability Scoring Details\n=============================\n\nCisco has provided scores for the vulnerabilities in this advisory\nbased on the Common Vulnerability Scoring System (CVSS). The CVSS\nscoring in this security advisory is done in accordance with CVSS\nversion 2.0. \n\nCVSS is a standards-based scoring method that conveys vulnerability\nseverity and helps determine urgency and priority of response. \n\nCisco has provided a base and temporal score. Customers can then\ncompute environmental scores to assist in determining the impact of\nthe vulnerability in individual networks. \n\nCisco has provided an FAQ to answer additional questions regarding\nCVSS at\n\nhttp://www.cisco.com/web/about/security/intelligence/cvss-qandas.html\n\nCisco has also provided a CVSS calculator to help compute the\nenvironmental impact for individual networks at\n\nhttp://intellishield.cisco.com/security/alertmanager/cvss\n\nCSCsl39126 - Malformed MGCP packet can crash device \n\nCVSS Base Score - 7.8\n Access Vector Network\n Access Complexity Low\n Authentication None\n Confidentiality Impact None\n Integrity Impact None\n Availability Impact Complete\n\nCVSS Temporal Score - 6.4\n Exploitability Functional\n Remediation Level Official Fix\n Report Confidence Confirmed\n\nCSCsk32606 - Malformed SIP packet can crash device \nCSCsk40030 - Malformed Session Attribute can crash device\nCSCsk38165 - Device crash during SIP testing\nCSCsk44115 - Device crash while processing overly long message\nCSCsj98521 - Device crash while processing malformed Contact Header\nCSCsk04588 - Device crash while processing malformed header\nCSCsz13590 - Malformed SIP header can crash device\n\nCVSS Base Score - 7.8\n Access Vector Network\n Access Complexity Low\n Authentication None\n Confidentiality Impact None\n Integrity Impact None\n Availability Impact Complete\n\nCVSS Temporal Score - 6.4\n Exploitability Functional\n Remediation Level Official Fix\n Report Confidence Confirmed\n\nCSCsk13561 - Exhaustion of TCP sockets prevents device from accepting\n new connections\n\nCVSS Base Score - 7.8\n Access Vector Network\n Access Complexity Low\n Authentication None\n Confidentiality Impact None\n Integrity Impact None\n Availability Impact Complete\n\nCVSS Temporal Score - 6.4\n Exploitability Functional\n Remediation Level Official Fix\n Report Confidence Confirmed\n\nImpact\n======\n\nSuccessful exploitation of all but one vulnerability in this advisory\ncan crash the affected device. The remaining vulnerability will not\ncrash the affected device, but it can lead to a DoS condition in\nwhich no new TCP-based connections will be accepted or created. \n\nSoftware Versions and Fixes\n===========================\n\nWhen considering software upgrades, also consult \nhttp://www.cisco.com/go/psirt and any subsequent advisories to \ndetermine exposure and a complete upgrade solution. \n\nIn all cases, customers should exercise caution to be certain the\ndevices to be upgraded contain sufficient memory and that current\nhardware and software configurations will continue to be supported\nproperly by the new release. If the information is not clear, contact\nthe Cisco Technical Assistance Center (TAC) or your contracted\nmaintenance provider for assistance. \n\nAll vulnerabilities listed in this Security Advisory are addressed in\nCisco PGW 2200 Softswitch version 9.7(3)S11, version 9.8(1)S5, and\nsubsequent, software releases. \n\nWorkarounds\n===========\n\nThere are no workarounds for the vulnerabilities in this advisory. \n\nIn the case of the vulnerability that corresponds to Cisco Bug ID\nCSCsk13561, administrator must manually reboot the affected device to\nrestore the device\u0027s ability to accept new connections. Because\nvulnerability prevents new TCP-based session to be created, this\nreboot can be initiated only from the console. If a failover device\nis configured, existing sessions will continue while the affected\ndevice is reloading. Without a failover device, all active sessions\nwill be terminated while the affected device is reloading. \n\nAdditional mitigation techniques that can be deployed on Cisco\ndevices within the network are available in the Cisco Applied\nMitigation Bulletin companion document for this advisory: \nhttp://www.cisco.com/warp/public/707/cisco-amb-20100512-pgw.shtml\n\nObtaining Fixed Software\n========================\n\nCisco has released free software updates that address these\nvulnerabilities.
