CVE-2024-11018
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 · uneditedWebopac from Grand Vice info does not properly validate uploaded file types, allowing unauthenticated remote attackers to upload and execute webshells, which could lead to arbitrary code execution 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 · moderate confidenceWebopac from Grand Vice info lacks proper file type validation in its upload functionality, allowing unauthenticated attackers to upload arbitrary files including webshells. This improper input validation enables remote code execution on the affected server.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify the installed Webopac versionAccess the Webopac admin interface, check the About/Help section, or query the application's version endpoint or configuration files for the version numberAffected if The installed version is >= 6 and < 6.5.1, or >= 7 and < 7.2.3
-
Confirm the file upload feature is enabledLocate the upload functionality in the Webopac interface or examine the application's routing configuration to verify upload endpoints are activeAffected if The upload module is accessible and not explicitly disabled in the application configuration
-
Inspect the upload file type validation configurationExamine the application's upload handler code or configuration settings to determine what file type validation is performed on uploaded filesAffected if The application lacks proper file type validation (magic byte verification and extension whitelisting) in the upload processing logic
-
Verify upload directory placementCheck the server filesystem and web server configuration to determine where uploaded files are stored relative to the web rootAffected if Uploaded files are stored within the webroot directory tree
-
Check script execution permissions on upload directoriesReview the web server configuration (Apache .htaccess, Nginx settings, or equivalent) for the upload directory to see if script execution is restrictedAffected if Script execution is allowed in the directory where uploads are stored
A user is affected if their Webopac version falls within the affected ranges AND the upload feature is enabled with insufficient validation controls.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped6.5.17.2.3
Implement strict file type validation using magic byte verification and whitelist allowed extensions; store uploaded files outside webroot; disable script execution in upload directories.
Webopac 6.5.1 or later (for 6.x branch); Webopac 7.2.3 or later (for 7.x branch)
- 1. Identify the currently installed Webopac version by checking the application or system documentation
- 2. For Webopac version 6.x users: Plan upgrade to version 6.5.1 or later
- 3. For Webopac version 7.x users: Plan upgrade to version 7.2.3 or later
- 4. Before upgrading, perform a complete backup of the Webopac application, database, and configuration files
- 5. Review upgrade documentation provided by Grand Vice info for any specific migration requirements
- 6. Apply the upgrade to the appropriate fixed version (6.5.1+ or 7.2.3+) following vendor instructions
- 7. After upgrade, verify that file upload functionality properly validates file types (e.g., MIME type, file extension, content inspection)
- 8. Confirm the arbitrary code execution vulnerability is remediated by testing with authorized file uploads only
