      "value": "ChurchCRM is an open-source church management system. Prior to 6.5.3, a path traversal vulnerability in ChurchCRM's backup restore functionality allows authenticated administrators to upload arbitrary files and achieve remote code execution by overwriting Apache .htaccess configuration files. The vulnerability exists in src/ChurchCRM/Backup/RestoreJob.php. The $rawUploadedFile['name'] parameter is user-controlled and allows uploading files with arbitrary names to /var/www/html/tmp_attach/ChurchCRMBackups/. This vulnerability is fixed in 6.5.3."

      "value": "ChurchCRM es un sistema de gestión de iglesias de código abierto. Antes de 6.5.3, una vulnerabilidad de salto de ruta en la funcionalidad de restauración de copias de seguridad de ChurchCRM permite a los administradores autenticados subir archivos arbitrarios y lograr la ejecución remota de código sobrescribiendo los archivos de configuración .htaccess de Apache. La vulnerabilidad existe en src/ChurchCRM/Backup/RestoreJob.PHP. El parámetro $rawUploadedFile[’name’] es controlado por el usuario y permite subir archivos con nombres arbitrarios a /var/www/html/tmp_attach/ChurchCRMBackups/. Esta vulnerabilidad se corrigió en 6.5.3."
