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
An authentication bypass vulnerability in the ODBC App Server of Progress MarkLogic Server before 11.3.6 and 12.0.3 allows an unauthenticated remote attacker to bypass password verification and execute queries with the privileges of any named user known to the server, including administrators.

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.

How this class of weakness works · CWE-287

The mechanism that verifies who a user is can be side-stepped or fooled, letting an attacker act as someone they're not. Everything built on top of that identity then becomes untrustworthy. Fixing it means hardening the full authentication flow, including edge cases, tokens, and secondary paths.

Recommended fix High confidence

Upgrade to MarkLogic Server 11.3.6 or 12.0.3 (or later)

  1. 1. Back up the current MarkLogic database, configuration, and application data before starting the upgrade process.
  2. 2. Review the Progress MarkLogic Server 11.3.6 or 12.0.3 release notes for any changes, deprecations, or migration requirements relevant to your deployment.
  3. 3. Stop all MarkLogic Server processes and services to ensure a clean upgrade.
  4. 4. Upgrade MarkLogic Server to version 11.3.6 (for 11.x branch) or 12.0.3 (for 12.x branch), following the standard upgrade procedures for your operating system.
  5. 5. After upgrading, restart MarkLogic Server and verify all services are running correctly.
  6. 6. Test the ODBC App Server functionality to confirm queries now require proper authentication.
  7. 7. Verify that unauthenticated access to the ODBC App Server is no longer possible and that password verification is enforced for all users.
Caveat Review release notes for your target version to check for any breaking changes or deprecated features; major version upgrades may require configuration or application changes
