Affected Products

Vulnerable Products

Cisco Unified MeetingPlace versions 5, 6, and 7 are each affected by at least one of the vulnerabilities described in this document.

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.

Cisco MeetingTime is a desktop application included with Cisco Unified MeetingPlace version 6.x that could be used to access and configure the Cisco Unified MeetingPlace Audio Server systems. MeetingTime classifies users as either end users, contacts, attendants, or system administrators.

The end-of-software maintenance for MeetingPlace version 5.3 occurred in April 2009. End-of-sale and end-of-life details are available at:

http://www.cisco.com/en/US/prod/collateral/voicesw/ps6789/ps5664/ps5669/prod_end-of-life_notice0900aecd806e743c.html

Products Confirmed Not Vulnerable

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

Details

This Security Advisory describes multiple distinct vulnerabilities in the MeetingPlace and MeetingTime products. These vulnerabilities are independent of each other.

Insufficient Validation of SQL Commands

An unauthenticated user may be able to send SQL commands to manipulate the database that MeetingPlace uses to store information about server configuration, meetings, and users. These commands could be used to create, delete, or alter any of the information contained in the Cisco Unified MeetingPlace database.

This vulnerability is documented in Cisco Bug ID CSCtc39691 ( registered customers only) and has been assigned CVE ID CVE-2010-0139.

Unauthorized Account Creation

An unauthenticated user may be able to send a crafted URL to the internal interface of the Cisco Unified MeetingPlace web server to create a MeetingPlace user or administrator account.

This vulnerability is documented in Cisco Bug IDs CSCtc59231 ( registered customers only) and CSCtd40661 ( registered customers only) and has been assigned CVE ID CVE-2010-0140.

User and Password Enumeration in Cisco MeetingTime

The MeetingTime authentication sequence consists of a series of packets that are transmitted between the client and the Cisco Meeting Place Audio Server over TCP port 5001. An attacker may be able to alter the authentication sequence to access sensitive information in the user database including usernames and passwords.

This vulnerability is documented in Cisco Bug ID CSCsv76935 ( registered customers only) and has been assigned CVE ID CVE-2010-0141.

Privilege Escalation in Cisco MeetingTime

An attacker may be able to alter the packets in the MeetingTime authentication sequence to elevate the privileges of a normal user to an administrative user.

This vulnerability is documented in Cisco Bug ID CSCsv66530 ( registered customers only) and has been assigned CVE ID CVE-2010-0142.

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:

Workarounds

There are no workarounds for the vulnerabilities described in this advisory.

Obtaining Fixed Software

Cisco has released free software updates that address these vulnerabilities. Prior to deploying software, customers should consult their maintenance provider or check the software for feature set compatibility and known issues specific to their environment.

Customers may only install and expect support for the feature sets they have purchased. By installing, downloading, accessing or otherwise using such software upgrades, customers agree to be bound by the terms of Cisco's software license terms found at http://www.cisco.com/en/US/docs/general/warranty/English/EU1KEN_.html, or as otherwise set forth at Cisco.com Downloads at http://www.cisco.com/public/sw-center/sw-usingswc.shtml.

Do not contact psirt@cisco.com or security-alert@cisco.com for software upgrades.

Customers using Third Party Support Organizations

Customers whose Cisco products 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 support organization for guidance and assistance with the appropriate course of action in regards to this advisory.

The effectiveness of any workaround or fix is dependent on specific customer situations, such as product mix, network topology, traffic behavior, and organizational mission. Due to the variety of affected products and releases, customers should consult with their service provider or support organization to ensure any applied workaround or fix is the most appropriate for use in the intended network before it is deployed.

Customers without Service Contracts

Customers who purchase direct from Cisco but do not hold a Cisco service contract, and customers who purchase through third-party vendors but are unsuccessful in obtaining fixed software through their point of sale should acquire upgrades by contacting the Cisco Technical Assistance Center (TAC). TAC contacts are as follows.
