CyberRota Analysis
AI-GeneratedThe Bulk Order Update for WooCommerce plugin for WordPress is vulnerable to arbitrary file read attacks, allowing unauthenticated users to access the first line of sensitive files on the server, such as /etc/passwd. This vulnerability arises from inadequate checks in the AJAX handler, which improperly processes user-supplied input. WordPress site administrators using this plugin should prioritize patching to mitigate potential data exposure risks.
Original NVD Description
The Bulk Order Update for WooCommerce plugin for WordPress is vulnerable to Arbitrary File Read in versions up to, and including, 1.6. This is due to the bouw_fetch_csv_data() AJAX handler being registered on the wp_ajax_nopriv_ hook with no capability or nonce check, and passing the attacker-supplied csv_url POST parameter — filtered only by esc_url_raw() (which leaves absolute filesystem paths intact) and validate_file() (which only rejects '..' traversal patterns) — directly into fopen()/fgetcsv() and reflecting the first parsed line in the JSON response. This makes it possible for unauthenticated attackers to read the first line of arbitrary files on the server (such as /etc/passwd) and to use the handler as a file-existence oracle.
