Multiple Vulnerabilities in Cisco Unified MeetingPlace Web Conferencing

Advisory ID: cisco-sa-20121031-mp

http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20121031-mp

Revision 1.1

Last Updated  2012 November 27 14:29  UTC (GMT)

For Public Release 2012 October 31 16:00  UTC (GMT)


Summary

Cisco Unified MeetingPlace Web Conferencing is affected by two vulnerabilities:
  • Cisco Unified MeetingPlace Web Conferencing SQL Injection Vulnerability
  • Cisco Unified MeetingPlace Web Conferencing Buffer Overrun Vulnerability

Exploitation of the Cisco Unified MeetingPlace Web Conferencing SQL Injection Vulnerability may allow an unauthenticated, remote attacker to send Structured Query Language (SQL) commands to manipulate the MeetingPlace database stores information about server configuration, meetings, and users. These commands may be used to create, delete, or alter some of the information in the Cisco Unified MeetingPlace Web Conferencing database.

Exploitation of the Cisco Unified MeetingPlace Web Conferencing Buffer Overrun Vulnerability may allow an unauthenticated, remote attacker to create a buffer overrun condition that may cause the Web Conferencing server to become unresponsive.

Cisco has released free software updates that address these vulnerabilities. There are no workarounds that mitigate these vulnerabilities. This advisory is available at the following link:

Products Confirmed Not Vulnerable

No other Cisco products are currently known to be affected by these vulnerabilities.

Details

The Cisco Unified MeetingPlace conferencing solution provides functionality that allows organizations to host integrated voice, video, and web conferencing. The solution is deployed on network and integrated directly into an organization's private voice/data networks and enterprise applications. Cisco Unified MeetingPlace servers can be deployed so that the server is accessible from the Internet, allowing external parties to participate in meetings.

Web Conferencing is a core component of the Cisco Unified MeetingPlace conferencing solution that allows users to share applications and presentations and manage meetings.

Cisco Unified MeetingPlace Web Conferencing SQL Injection Vulnerability

The Cisco Unified MeetingPlace Web Conferencing service contains a vulnerability that could allow an unauthenticated, remote attacker to inject Structured Query Language (SQL) commands, that may affect the integrity and availability of the data stored in the MeetingPlace Web Conferencing internal database. This data may include server configurations, meetings, and users.
The vulnerability is due to insufficient validation of some of the parameters passed through the HTTP POST method. An attacker could exploit this vulnerability by inserting malicious SQL commands in the HTTP POST request directed to the affected system. An exploit could allow the attacker to modify or delete data from the Web Conferencing database.

This vulnerability is documented in Cisco bug ID CSCtx08939 ( registered customers only) and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2012-0337

Cisco Unified MeetingPlace Web Conferencing Buffer Overrun Vulnerability


The Cisco Unified MeetingPlace Web Conferencing service contains a vulnerability that could allow an unauthenticated, remote attacker to create a buffer overrun condition that may cause the Web Conferencing server to become unresponsive.
The vulnerability is due to insufficient validation of some parameter values of an HTTP POST request. An attacker may be able to exploit this vulnerability by crafting the value of the vulnerable parameters in an HTTP POST request directed to the affected system. An exploit could allow the attacker to cause the Web Conferencing server to become unresponsive.

This vulnerability is documented in Cisco bug ID CSCua66341 ( registered customers only) and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2012-5416

Vulnerability Scoring Details

Cisco has scored the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this security advisory is in accordance with CVSS version 2.0.

CVSS is a standards-based scoring method that conveys vulnerability severity and helps organizations determine the urgency and priority of a response.

Cisco has provided a base and temporal score. Customers can also compute environmental scores that help determine the impact of the vulnerability in their own networks.

Cisco has provided additional information regarding CVSS at the following link:

http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html

Cisco has also provided a CVSS calculator to compute the environmental impact for individual networks at the following link:

Obtaining Fixed Software

Cisco has released free software updates that address the vulnerabilities described in this advisory. Prior to deploying software, customers are advised to consult their maintenance providers or check the software for feature set compatibility and known issues that are specific to their environments.

Customers may only install and expect support for feature sets they have purchased. By installing, downloading, accessing, or otherwise using such software upgrades, customers agree to follow the terms of the Cisco software license at http://www.cisco.com/en/US/docs/general/warranty/English/EU1KEN_.html.

Customers with Service Contracts

Customers with contracts should obtain upgraded software through their regular update channels. For most customers, upgrades should be obtained through the Software Navigator on Cisco.com at http://www.cisco.com/cisco/software/navigator.html.

Customers using Third Party Support Organizations

Customers with Cisco products that are provided or maintained through prior or existing agreements with third-party support organizations, such as Cisco Partners, authorized resellers, or service providers, should contact that organization for assistance with the appropriate course of action.

The effectiveness of any workaround or fix depends on specific customer situations, such as product mix, network topology, traffic behavior, and organizational mission. Because of the variety of affected products and releases, customers should consult their service providers or support organizations to ensure that any applied workaround or fix is the most appropriate in the intended network before it is deployed.

Customers without Service Contracts

Customers 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 Technical Assistance Center (TAC):

  • +1 800 553 2447 (toll free from within North America)
  • +1 408 526 7209 (toll call from anywhere in the world)
