Message-id: <201001271130.mp@psirt.cisco.com> Date: Wed, 27 Jan 2010 11:30:00 -0500 From: Cisco Systems Product Security Incident Response Team <psirt@...co.com> To: full-disclosure@...ts.grok.org.uk Cc: psirt@...co.com Subject: Cisco Security Advisory: Multiple Vulnerabilities in Cisco Unified MeetingPlace -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Cisco Security Advisory: Multiple Vulnerabilities in Cisco Unified MeetingPlace Advisory ID: cisco-sa-20100127-mp Revision 1.0 For Public Release 2010 Jan 27 1600 UTC (GMT) +--------------------------------------------------------------------- Summary ======= Multiple vulnerabilities exist in Cisco Unified MeetingPlace. This security advisory outlines the details of these vulnerabilities: * Insufficient validation of SQL commands * Unauthorized account creation * User and password enumeration in Cisco MeetingTime * Privilege escalation in Cisco MeetingTime Workarounds are not available for these vulnerabilities. This advisory is posted at: http://www.cisco.com/warp/public/707/cisco-sa-20100127-mp.shtml 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://cco-rtp-1.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 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: http://intellishield.cisco.com/security/alertmanager/cvss CSCtc39691 - Insufficient validation of SQL commands CVSS Base Score - 9 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - Partial Integrity Impact - Partial Availability Impact - Complete CVSS Temporal Score - 7.8 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed CSCtc59231/CSCtd40661 - Unauthorized account creation CVSS Base Score - 10 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - Complete Integrity Impact - Complete Availability Impact - Complete CVSS Temporal Score - 8.7 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed CSCsv76935 - User and password enumeration in Cisco MeetingTime CVSS Base Score - 6.4 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - Partial Integrity Impact - Partial Availability Impact - None CVSS Temporal Score - 5.3 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed CSCsv66530 - Privilege escalation in Cisco MeetingTime CVSS Base Score - 8.5 Access Vector - Network Access Complexity - Medium Authentication - Single Confidentiality Impact - Complete Integrity Impact - Complete Availability Impact - Complete CVSS Temporal Score - 7.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== Successful exploitation of these vulnerabilities may result in a variety of conditions including: information disclosure, denial of service, privilege escalation, account creation, or alteration of configuration data. Software Versions and Fixes =========================== The following table identifies the version of software in which each vulnerability was first fixed. The latest versions of Cisco MeetingPlace software can be downloaded from: http://tools.cisco.com/support/downloads/go/Redirect.x?mdfid=278785523 +---------------------------------------------+ | Vulnerability | MeetingPlace | MeetingPlace | | | 6 | 7 | |---------------+--------------+--------------| | Insufficient | | 7.0(2.3) | | validation of | 6.0.639.2 | hotfix 5F | | SQL commands | | | |---------------+--------------+--------------| | Unauthorized | | 7.0(2.3) | | account | 6.0.639.3 | hotfix 5F | | creation | | | |---------------+--------------+--------------| | User and | | | | password | | Not | | enumeration | MR5 | applicable | | in Cisco | | | | MeetingTime | | | |---------------+--------------+--------------| | Privilege | | Not | | escalation in | MR5 | applicable | | MeetingTime | | | +---------------------------------------------+ When considering software upgrades, also consult: http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution.
