webandprint vulnerabilities and threats

The AR for WooCommerce plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 8.40 via the 'file' parameter parameter. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information. The three intended access controls all fail: valid nonces are freely minted by unauthenticated callers via the nopriv ar_get_fresh_nonce and ar_process_user_image AJAX handlers; the AES-256-CBC encryption key is derived from get_option('ar_licence_key'), which returns false on default free installations and yields a predictable key attackers can use to encrypt their own path payloads; and the Referer check is trivially bypassed because the Referer header is attacker-controlled.

The AR for WordPress plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 8.40 via the 'file' parameter parameter. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information. Exploitation requires an attacker to first obtain a valid nonce and secure nonce via the publicly accessible ar_get_fresh_nonce and ar_process_user_image nopriv AJAX handlers, and to reproduce the encryption key locally — both steps are fully achievable by an unauthenticated attacker on any default free or unlicensed installation where ar_licence_key is unset.

Cross-Site Request Forgery (CSRF) vulnerability in webandprint AR For WordPress ar-for-wordpress allows Upload a Web Shell to a Web Server.This issue affects AR For WordPress: from n/a through <= 8.34.

The AR for WordPress plugin for WordPress is vulnerable to unauthorized double extension file upload due to a missing capability check on the set_ar_featured_image() function in all versions up to, and including, 7.3. This makes it possible for unauthenticated attackers to upload php files leveraging a double extension attack. It's important to note the file is deleted immediately and double extension attacks only work on select servers making this unlikely to be successfully exploited.
