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
Unrestricted Upload of File with Dangerous Type vulnerability in Apache Answer. This issue affects Apache Answer: through 2.0.0. A crafted TIFF image could trigger excessive memory allocation during image decoding, allowing an authenticated user to cause the server process to crash. Users are recommended to upgrade to version 2.0.1, which fixes the issue.

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

An authenticated user can upload a crafted TIFF image that triggers excessive memory allocation during image decoding, causing the server process to crash due to denial of service.

MitigationUpgrade Apache Answer to version 2.0.1 or later. Consider implementing image file validation and memory limits on uploads as additional hardening.

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. Check Apache Answer version
    Locate and inspect the version file or check the version displayed in the Answer admin panel under System > About, or run 'answer version' if the CLI is available
    Affected if The installed version is any release prior to 2.0.1, including all 2.0.0 and earlier versions
  2. Confirm image upload functionality is enabled
    Navigate to the admin dashboard and inspect the Upload settings under Content or Storage configuration. Check if image/file upload permissions are granted to user roles
    Affected if Image or file upload is enabled for any authenticated user role (including regular users, moderators, or custom roles)
  3. Verify user authentication is active
    Check the authentication settings in the admin panel under Users > Registration or examine whether the login/registration pages are publicly accessible
    Affected if Public user registration is enabled or existing authenticated users can log in to the platform

You are affected if Apache Answer version is below 2.0.1 AND image upload is enabled AND user authentication is active, as the combination allows authenticated users to upload malicious TIFF files that crash the server process.

Upgrade available Upgrade to 2.0.1 or later
Fixed in 2.0.1
Interim mitigation

Upgrade Apache Answer to version 2.0.1 or later. Consider implementing image file validation and memory limits on uploads as additional hardening.

Recommended fix High confidence

2.0.1

  1. 1. Back up the current Apache Answer installation and database before proceeding
