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:

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.
