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
A vulnerability in Cisco Connected Mobile Experiences (CMX) could allow a remote, authenticated attacker without administrative privileges to alter the password of any user on an affected system. The vulnerability is due to incorrect handling of authorization checks for changing a password. An authenticated attacker without administrative privileges could exploit this vulnerability by sending a modified HTTP request to an affected device. A successful exploit could allow the attacker to alter the passwords of any user on the system, including an administrative user, and then impersonate that user.

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

Cisco CMX contains an authorization bypass vulnerability where authenticated users without administrative privileges can modify passwords of any user on the system, including administrative accounts. The flaw resides in the password change functionality which fails to properly validate authorization level before allowing password modifications via modified HTTP requests.

MitigationApply the relevant Cisco security patch for CVE-2021-1144 or upgrade to a patched version of Cisco CMX. Verify that non-administrative users cannot modify other users' passwords after remediation.

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. Identify Cisco CMX installation and version
    Locate the Cisco CMX installation and determine its exact version number. This is typically available via the web administration interface (usually at /admin) or via CLI commands such as 'show version' or 'show system info' on the CMX appliance.
    Affected if The installed version is 10.6.0, 10.6.1, or 10.6.2
  2. Verify non-administrative user accounts exist
    Log in to the Cisco CMX web interface or check the user database to confirm that there is at least one authenticated user without administrative privileges.
    Affected if Non-admin user accounts are present in the system
  3. Confirm password change functionality is accessible
    Access the password change or user management section of the Cisco CMX web interface while logged in as a non-administrative user. Attempt to navigate to endpoints or forms that allow password modifications for other users.
    Affected if The password change functionality is accessible to authenticated users without admin rights
  4. Test authorization bypass on password modification
    Using a non-administrative user session, attempt to modify the password of another user (including an administrator account) by intercepting and modifying the HTTP request parameters to target a different user account.
    Affected if A non-admin user can successfully change another user's password, including administrative accounts

The environment is affected if Cisco CMX version 10.6.0, 10.6.1, or 10.6.2 is running and authenticated non-administrative users can modify passwords of other users through the password change functionality without proper authorization validation.
