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
Zenphoto versions prior to 1.5.7 allows an attacker to conduct PHP code injection attacks by leading a user to upload a specially crafted .zip file.

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

Zenphoto versions before 1.5.7 are vulnerable to PHP code injection via malicious .zip file uploads. An attacker can upload a specially crafted archive containing PHP files that get executed on the server, leading to remote code execution.

MitigationUpgrade to Zenphoto 1.5.7 or later. Until then, disable file upload functionality or implement strict file type validation that prevents execution of any uploaded content and restricts uploads to safe file types only.

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. Determine installed Zenphoto version
    Access the Zenphoto admin panel and navigate to the Dashboard or About page to view the installed version. Alternatively, check the version.php file in the Zenphoto root directory if you have file system access.
    Affected if Version is displayed as less than 1.5.7 (for example, 1.5.6, 1.5.5, or earlier)
  2. Verify if file upload functionality is enabled
    Log in to the Zenphoto admin panel and go to Options or Settings. Look for upload-related settings such as 'Upload allowed', 'Enable uploads', or similar options under the security or upload sections.
    Affected if File upload functionality is turned ON or enabled
  3. Check if .zip file uploads are permitted
    In the Zenphoto admin panel under Options or Settings, examine the allowed file extensions or upload restrictions. Look for settings that control which file types can be uploaded.
    Affected if .zip extension is listed among allowed upload types, or no extension restrictions are configured

You are affected if your Zenphoto installation is version 1.5.6 or earlier AND file uploads (including .zip files) are enabled in your configuration.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.
