Cost Calculator Builder Pro

The Cost Calculator Builder PRO plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 4.0.3 via the js_to_php function. This is due to insufficient sanitization of the orderDetails[*].originalValue field, which is injected verbatim into a calculator formula string passed to PHP eval() inside js_to_php(), with the regex allow-list in evaluateFormula() only filtering alphanumeric tokens and leaving non-word punctuation characters intact. This makes it possible for unauthenticated attackers to execute code on the server. The only authentication barrier is a nonce check, but the required nonce is publicly emitted on every front-end page via the wp_head hook, making it freely obtainable by unauthenticated visitors. Payloads must be non-word XOR gadgets to bypass sanitization.

The Cost Calculator Builder PRO plugin for WordPress is vulnerable to price manipulation in all versions up to, and including, 3.2.1. This is due to the plugin allowing the price field to be manipulated prior to processing via the 'create_cc_order' function, called from the Cost Calculator Builder plugin. This makes it possible for unauthenticated attackers to manipulate the price of orders submitted via the calculator. Note: this vulnerability was partially patched with the release of Cost Calculator Builder version 3.2.17.

Cost Calculator Builder Pro plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to 3.1.72, via the send_demo_webhook() function.

The Cost Calculator Builder PRO for WordPress is vulnerable to arbitrary email sending vulnerability in versions up to, and including, 3.1.75. This is due to insufficient limitations on the email recipient and the content in the 'send_pdf' and the 'send_pdf_front' functions which are reachable via AJAX. This makes it possible for unauthenticated attackers to send emails with any content to any recipient.

The Cost Calculator Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the SVG upload feature in all versions up to, and including, 3.1.67 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
