Advisory

Source description from Wordfence Intelligence, credited to Sarvar Eshboyev.

The JetBackup – Backup, Restore & Migrate plugin for WordPress is vulnerable to Arbitrary File Write in all versions up to, and including, 3.1.24.9. This is due to missing destination-containment validation on symlink targets during archive extraction in the SYMTYPE case of the extract method, allowing symlinks pointing outside the extraction directory to be created without restriction. This makes it possible for authenticated attackers, with admin-level access and above, to write attacker-controlled file contents to arbitrary locations on the server by including a maliciously crafted symbolic link in a backup archive, potentially leading to remote code execution. The attacker must have administrator-level access to the WordPress installation and the ability to import or restore a crafted backup archive.
