Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The password-change feature in Cisco Unified MeetingPlace Web Conferencing before 8.5(5) MR3 and 8.6 before 8.6(2) does not check the session ID or require entry of the current password, which allows remote attackers to reset arbitrary passwords via a crafted HTTP request, aka Bug ID CSCuu51839.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

The password-change feature in Cisco Unified MeetingPlace Web Conferencing versions prior to 8.5(5) MR3 and 8.6(2) lacks proper authentication controls. The application does not validate the session ID or require the user's current password before allowing a password change, enabling remote attackers to reset arbitrary user passwords via crafted HTTP requests.

MitigationApply the vendor patch by upgrading to Cisco Unified MeetingPlace 8.5(5) MR3, 8.6(2), or later. If immediate patching is not feasible, implement network-level access controls to restrict the password change endpoint and monitor for anomalous password reset activity.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Cisco Unified MeetingPlace Web Conferencing is installed
    Check running web services on the server or review installed software for 'Cisco Unified MeetingPlace' or 'MeetingPlace' components
    Affected if The application is present on the system
  2. Determine the installed version
    Access the web admin interface or check system files for the version number. Compare against the affected list: 6.0.417.0, 6.0_base, 7.0(1), 7.0(2), 7.0(2)_sr1, 7.0(3), 7.1(1), 7.1(2), 8.0(1), 8.0(1)_sr1, 8.0(2), 8.5(1)
    Affected if The installed version matches any of the affected versions listed or is earlier than 8.5(5) MR3 or 8.6(2)
  3. Locate the password change endpoint
    Identify the HTTP endpoint used for password reset operations in the web application (typically /password or /changePassword paths in the web interface)
    Affected if The password change functionality is accessible via HTTP without authentication verification
  4. Test password change without authentication
    Send a crafted HTTP POST request to the password change endpoint with a new password parameter for a known user account without providing current password or session credentials
    Affected if The request succeeds and changes the password without requiring the user's current password or valid session ID

The environment is affected if Cisco Unified MeetingPlace Web Conferencing is running a version prior to 8.5(5) MR3 or 8.6(2) and the password change endpoint accepts requests without validating the session or current password.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply the vendor patch by upgrading to Cisco Unified MeetingPlace 8.5(5) MR3, 8.6(2), or later. If immediate patching is not feasible, implement network-level access controls to restrict the password change endpoint and monitor for anomalous password reset activity.

Recommended fix High confidence

Upgrade to Cisco Unified MeetingPlace 8.5(5) MR3 or later, or 8.6(2) or later

  1. 1. Identify the current version of Cisco Unified MeetingPlace Web Conferencing by accessing the admin interface or using system commands
  2. 2. Plan an upgrade to one of the following fixed releases: 8.5(5) MR3 or later, OR 8.6(2) or later
  3. 3. Create a complete backup of the current system configuration and database
  4. 4. Review Cisco's official upgrade documentation for your current version to ensure compatibility
  5. 5. Schedule a maintenance window to perform the upgrade
  6. 6. Execute the upgrade following Cisco's documented procedures
  7. 7. After upgrade, verify the system is operational and confirm the password change feature now properly validates session IDs and requires current password entry
Caveat Review Cisco release notes for potential compatibility issues between your current version and the target upgrade version before proceeding
