Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in JetBackup JetBackup – WP Backup, Migrate & Restore plugin <= 1.6.9.0 versions.

The JetBackup – WP Backup, Migrate & Restore plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including 1.3.9. This is due to missing nonce validation on the backup_guard_get_import_backup() function. This makes it possible for unauthenticated attackers to upload arbitrary files to the vulnerable site's server via a forged request, granted they can trick a site's administrator into performing an action such as clicking on a link.

The JetBackup – WP Backup, Migrate & Restore plugin for WordPress is vulnerable to sensitive information disclosure in versions up to, and including, 1.4.0 due to a lack of proper capability checking on the backup_guard_get_manual_modal function called via an AJAX action. This makes it possible for subscriber-level attackers, and above, to invoke the function and obtain database table information.

The JetBackup – WP Backup, Migrate & Restore plugin for WordPress is vulnerable to unauthorized back-up location changes in versions up to, and including 1.4.1 due to a lack of proper capability checking on the backup_guard_cloud_dropbox, backup_guard_cloud_gdrive, and backup_guard_cloud_oneDrive functions. This makes it possible for authenticated attackers, with minimal permissions, such as a subscriber to change to location of back-ups and potentially steal sensitive information from them.
