What the vulnerability does
The Woffice Core plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the woffice_file_manager_delete() function in all versions up to, and including, 5.4.26. This makes it possible for authenticated attackers, with Contributor-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php).
Explanation of Vulnerability in Simple Terms
Woffice Core versions up to 5.4.26 contain a path traversal vulnerability that allows authenticated users to manipulate file paths and modify or delete files on the server. The vulnerability requires low-level authentication and high attack complexity, but successful exploitation can compromise site integrity and availability. Update to a version newer than 5.4.26 to remediate.
What an attacker can do
Modify or delete files on the server by traversing the file system through crafted path inputs.
Potential impact on your site
An authenticated attacker can corrupt or remove critical site files, causing data loss or service disruption.
Conditions required to exploit
Attacker must have a low-privilege user account on the site; no user interaction required.
