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
Incorrect access control in writercms v1.1.0 allows attackers to directly obtain backend account passwords via unspecified vectors.

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 · moderate confidence

WriterCMS v1.1.0 contains an incorrect access control vulnerability that allows unauthenticated attackers to directly retrieve backend account passwords. The vulnerability stems from improper authorization checks that fail to protect sensitive credential storage or transmission, enabling password exposure without authentication. Given the CVSS score of 7.5 and high attack vector availability, this represents a significant authentication bypass affecting the CMS backend.

MitigationImmediate actions include restricting backend access to authorized IP ranges, implementing proper authentication middleware, ensuring passwords are hashed with salted algorithms (e.g., bcrypt), and reviewing all endpoints for authorization flaws. Upgrading to a patched version if available and conducting a full access control audit is strongly recommended.

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 WriterCMS version
    Locate and inspect the version file or header typically found in the CMS installation (commonly version.php, or check the main index page source/meta tags for version disclosure)
    Affected if The installed version is exactly 1.1.0 of WriterCMS
  2. Identify backend accessibility
    Determine if the /admin, /backend, or administrative paths are reachable from the public internet (scan network logs or test direct URL access from an external host)
    Affected if Administrative interfaces are exposed without IP restrictions or VPN wrapping
  3. Test unauthenticated endpoint access
    Attempt to access suspected credential or user endpoints (such as /api/users, /user/list, or similar paths that return account data) without providing any login credentials
    Affected if Sensitive endpoints return password or credential data without requiring authentication
  4. Inspect HTTP response headers and body
    Capture and review responses from backend-related requests for any exposed plaintext passwords, hashed credentials, or user data that should require authorization
    Affected if Responses contain plaintext passwords or expose backend account credentials to unauthenticated requesters

If WriterCMS version 1.1.0 is running and administrative or user endpoints are accessible without authentication and return password data, the environment is affected by CVE-2023-43905.
