CVE-2026-75949
CriticalCVSS 10.0Summary
The J-BusinessDirectory extension for Joomla before version 6.2.3 contains a vulnerability allowing arbitrary file upload/deletion via path traversal. The _path_type parameter can point to component site/admin trees, and the extension check is weak. CSRF token is also missing on upload/remove.
Risk Assessment
An attacker can upload or delete arbitrary files on the server, potentially leading to full site compromise or destruction.
Recommendation
Update J-BusinessDirectory to version 6.2.3 or later. Additionally, implement file integrity monitoring and enforce CSRF tokens.
Original NVD description (English source)
Joomla Extension - cmsjunkie.com - Arbitrary file upload / deletion (path traversal) in J-BusinessDirectory < 6.2.3 - Upload/remove accepted a client-controlled root (_path_type could point at the component site/admin trees), did not enforce path containment, and used a weak extension check. CSRF token was also missing on upload/remove.
