Administrator file upload via unchecked upload filename
Published Feb 22, 2025 · Updated Jun 4, 2026
Arbitrary file upload in WPvivid Backup & Migration 0.9.112 and earlier allows remote authenticated users to write server files. The upload_files function accepts an attacker-controlled filename, forces ZIP metadata during handling, and renames the completed chunk without validating its actual extension. Administrator access and a valid nonce are required; on NGINX, a PHP upload can be requested from the backup directory and executed, while Apache blocks access there.
