📄 Description (English)

The Database Backup for WordPress plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.5.2. This is due to the plugin not restricting access to the wp_db_temp_dir parameter, which controls where database backups are written. This makes it possible for unauthenticated attackers to send a request to wp-cron.php with a poisoned wp_db_temp_dir value pointing to a publicly accessible directory (e.g., wp-content/uploads/), and if a scheduled backup is due, intercept the backup file before it is cleaned up. The backup file has a predictable name based on the database name, table prefix, date, and Swatch Internet Time, making interception reliable. Successful exploitation leads to Sensitive Information Exposure including database credentials, user password hashes, and personally identifiable information. This vulnerability requires that the site administrator has configured scheduled backups.

🤖 AI Executive Summary

The Database Backup for WordPress plugin versions up to 2.5.2 contain an authorization bypass vulnerability allowing unauthenticated attackers to intercept database backup files containing sensitive information. Attackers can manipulate the wp_db_temp_dir parameter to redirect backups to publicly accessible directories and retrieve them before cleanup.

📄 Description (Arabic)
