CVE-2018-7665
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 · uneditedAn issue was discovered in ClipBucket before 4.0.0 Release 4902. A malicious file can be uploaded via the name parameter to actions/beats_uploader.php or actions/photo_uploader.php, or the coverPhoto parameter to edit_account.php.
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 analysisThe application accepts uploaded files without properly checking their type or content, so an attacker can upload something executable. If it lands where the server will run it, that is remote code execution. Remediating it means validating content rather than just the extension, storing uploads outside the web root, and never executing them.

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 · scopedClipBucket 4.0.0 Release 4902 or later
- 1. Back up your current ClipBucket installation including all uploaded media files and database.
- 2. Download ClipBucket version 4.0.0 Release 4902 or later from the official source (https://github.com/arslancb/ClipBucket or the official website).
- 3. Disable write access to the server during the upgrade process.
- 4. Replace the existing application files with the new version files, preserving your configuration files and custom assets.
- 5. Verify file permissions are correctly set after upgrade (typically 755 for directories, 644 for files, with write permissions for upload directories as needed).
- 6. Test the file upload functionality in actions/beats_uploader.php, actions/photo_uploader.php, and edit_account.php to confirm the vulnerability is remediated.
- 7. Ensure uploaded files are now properly validated and stored in allowed locations only.
