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:

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
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 
and CSCtd40661 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
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 
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:

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
