What the vulnerability does
01Description
The WP Customer Area plugin for WordPress is vulnerable to arbitrary file read and deletion due to insufficient file path validation in the 'ajax_attach_file' function in all versions up to, and including, 8.3.4. This makes it possible for authenticated attackers with a role that an administrator grants access to (e.g., Subscriber) to to read the contents of arbitrary files on the server, which can contain sensitive information, or 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
02Summary
WP Customer Area versions 8.3.4 and earlier contain a path traversal vulnerability that allows authenticated users to read, modify, or delete arbitrary files on the server. An attacker with low-level site access can exploit this without user interaction to access sensitive data, alter site files, or disrupt service. Update to a version newer than 8.3.4 immediately.
