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
Directory traversal vulnerability exists in a-blog cms Ver.3.1.x series versions prior to Ver.3.1.12, Ver.3.0.x series versions prior to Ver.3.0.32, Ver.2.11.x series versions prior to Ver.2.11.61, Ver.2.10.x series versions prior to Ver.2.10.53, and Ver.2.9 and earlier versions. If this vulnerability is exploited, a user with an editor or higher privilege who can log in to the product may obtain arbitrary files on the server.

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

Directory traversal vulnerability in a-blog cms allows authenticated users with editor privileges or higher to read arbitrary files on the server by manipulating file path parameters.

MitigationUpdate a-blog cms to Ver.3.1.12, Ver.3.0.32, Ver.2.11.61, or Ver.2.10.53 or later respectively to patch the vulnerability.

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 the installed a-blog cms version
    Check the version file or admin panel for the cms version. Typically found in the admin dashboard under 'システム設定' (System Settings) > 'バージョン情報' (Version Info), or check version.php in the installation directory.
    Affected if The installed version is < 2.10.53, OR >= 2.11.0 and < 2.11.61, OR >= 3.0.0 and < 3.0.32, OR >= 3.1.0 and < 3.1.12
  2. Verify if editor-level user accounts exist
    Access the user management section in the admin panel (usually under 'ユーザー管理' or 'ユーザー設定') and review the privilege levels assigned to users.
    Affected if Any user account has '編集者' (Editor) or higher privileges enabled in the cms
  3. Confirm user authentication is active
    Check that the cms user login function is accessible and functional. Verify that the 'config.php' or authentication module allows editor-level access.
    Affected if The built-in user authentication system is enabled and accessible to editor-level users
  4. Identify file-related functionality accessible to editors
    Review which modules or features are available to users with editor privileges, particularly any file download, export, or file path handling functions in the admin panel.
    Affected if Editor users have access to any file-related operations that accept path parameters

You are affected if your a-blog cms version falls within the vulnerable ranges AND editor-level user accounts exist with access to file-related functionality that handles path parameters.

Upgrade available Upgrade to 2.10.53 / 2.11.61 / 3.0.32 or later
Fixed in 2.10.532.11.613.0.32
Interim mitigation

Update a-blog cms to Ver.3.1.12, Ver.3.0.32, Ver.2.11.61, or Ver.2.10.53 or later respectively to patch the vulnerability.

Recommended fix High confidence

Upgrade to the latest version in your current branch: 2.10.53, 2.11.61, 3.0.32, or 3.1.12 respectively; or migrate to the latest stable release (currently 3.1.x)

  1. 1. Verify current a-blog cms version by checking the admin panel or version file
  2. 2. Identify which version branch is currently in use (2.10.x, 2.11.x, 3.0.x, or 3.1.x)
  3. 3. For 2.10.x branch: upgrade to version 2.10.53 or later
  4. 4. For 2.11.x branch: upgrade to version 2.11.61 or later
  5. 5. For 3.0.x branch: upgrade to version 3.0.32 or later
  6. 6. For 3.1.x branch: upgrade to version 3.1.12 or later
  7. 7. After upgrade, verify the fix by confirming file access restrictions work correctly
  8. 8. Test that legitimate editor-level operations still function properly
Caveat Standard upgrade precautions apply - backup database and files before upgrading; test in staging environment first
