WordPress Simple-Backup 2.7.11 Arbitrary File Deletion and Download

WordPress Simple-Backup 2.7.11 contains multiple vulnerabilities that allow unauthenticated attackers to delete arbitrary files and download sensitive files by manipulating the delete_backup_file and download_backup_file parameters in tools.php. Attackers can exploit insufficient input validation using directory traversal techniques to access wp-config.php, database dumps, and other sensitive files, or delete critical files .htaccess to expose backup directories.

Simple Backup <= 2.7.10 - Arbitrary File Download via Path Traversal

The Simple Backup plugin for WordPress is vulnerable to Arbitrary File Download in versions up to, and including, 2.7.10. via the download_backup_file function. This is due to a lack of capability checks and file type validation. This makes it possible for attackers to download sensitive files such as the wp-config.php file from the affected site.

Multiple cross-site scripting (XSS) vulnerabilities in the MyWebsiteAdvisor Simple Security plugin 1.1.5 and earlier for WordPress allow remote attackers to inject arbitrary web script or HTML via the (1) datefilter parameter in the access_log page to wp-admin/users.php or (2) simple_security_ip_blacklist[] parameter in an add_blacklist_ip action in the ip_blacklist page to wp-admin/users.php.
