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
Cisco Unity Connection before 7.1.3b(Su2) allows remote authenticated users to change the administrative password by leveraging the Help Desk Administrator role, aka Bug ID CSCtd45141.

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 Unity Connection versions prior to 7.1.3b(Su2) contain a privilege escalation vulnerability where a remote authenticated user with the Help Desk Administrator role can change the administrative password, effectively gaining full administrative control over the system.

MitigationUpgrade Cisco Unity Connection to version 7.1.3b(Su2) or later to remediate this vulnerability. If immediate upgrade is not possible, restrict Help Desk Administrator role assignments and monitor for unauthorized password changes.

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 Unity Connection installation
    Check if Cisco Unity Connection is installed on the system. This is typically found on Cisco Unified Communications Manager servers. Use 'show version' or check system documentation to confirm Unity Connection presence.
    Affected if Cisco Unity Connection is not installed on the system.
  2. Determine installed Unity Connection version
    Access the Cisco Unity Connection admin web interface or use CLI command 'show version' in the Cisco Unity Connection serviceability page to retrieve the exact version number.
    Affected if The installed version matches any of the following: versions prior to 7.1.3b(Su2), or versions 1.1, 1.1(1), 1.1(1)_es1, 1.1(1)_es12, 1.1(1)_sr1, 1.2, 1.2(1), 1.2(1)_es65, 1.2(1)sr2, 2.0, 2.0(1).
  3. Verify Help Desk Administrator role exists
    In Cisco Unity Connection admin interface, navigate to User Basics > User Templates > Role Management, or use CLI 'show cuc user role' to list defined roles including Help Desk Administrator.
    Affected if The Help Desk Administrator role is defined in the system.
  4. Check for Help Desk Administrator user accounts
    In Cisco Unity Connection admin interface, go to Users > Find to search for users assigned the Help Desk Administrator role, or use CLI 'show cuc user' to list users and their assigned roles.
    Affected if Any user account is assigned the Help Desk Administrator role.

A system is affected if Cisco Unity Connection is installed with a version listed in the affected versions range AND at least one user has the Help Desk Administrator role assigned.

Upgrade available Upgrade to a release after 7.1
Interim mitigation

Upgrade Cisco Unity Connection to version 7.1.3b(Su2) or later to remediate this vulnerability. If immediate upgrade is not possible, restrict Help Desk Administrator role assignments and monitor for unauthorized password changes.

Recommended fix High confidence

Cisco Unity Connection 7.1.3b(Su2) or later

  1. 1. Backup the current Cisco Unity Connection configuration and database before initiating any upgrade.
  2. 2. Download Cisco Unity Connection version 7.1.3b(Su2) or later from the Cisco Software Download Center (tools.cisco.com).
  3. 3. Review Cisco Unity Connection upgrade documentation and release notes for version 7.1.3b(Su2) for any prerequisites or migration requirements.
  4. 4. Schedule a maintenance window as upgrades may require system downtime.
  5. 5. Follow the standard Cisco Unity Connection upgrade procedure: run the upgrade installer, monitor for completion, and verify the new version is installed.
  6. 6. After upgrade, verify that the vulnerability is fixed by attempting to confirm the Help Desk Administrator role can no longer change administrative passwords.
  7. 7. Test critical Unity Connection services (voice messaging, call handlers, user access) to ensure normal operation.
Caveat Standard upgrade precautions apply - review release notes for any compatibility or migration considerations before proceeding
