What the vulnerability does
The Madara - Core plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the wp_manga_delete_zip() function in all versions up to, and including, 2.2.3. This makes it possible for unauthenticated attackers 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
Madara Core versions up to 2.2.3 contain a path traversal vulnerability that allows an attacker to modify or delete files on the server without authentication. By crafting malicious requests, an attacker can write or delete arbitrary files, potentially compromising the entire site. No user interaction is required to exploit this flaw.
What an attacker can do
Write or delete arbitrary files on the server without needing to log in.
Potential impact on your site
