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 unauthorized back-up location changes in versions up to, and including 1.4.1 due to a lack of proper capability checking on the backupguardclouddropbox, backupguardcloudgdrive, and backupguardcloudoneDrive 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.

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 backupguardgetimportbackup() 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 backupguardgetmanualmodal 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.
