At a glance
This record tracks a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the Request For Quote WordPress plugin, affecting versions < 1.3. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 1.3; sites on affected versions should update now. Disclosed July 2021, reported by WPScanTeam.
Vulnerability Overview
The Request for Quote plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions before 1.3. This is due to missing or incorrect nonce validation in the action_wpheka_add_to_quote and action_remove_item_from_rfq_list AJAX actions. This makes it possible for unauthenticated attackers to perform restricted administrative actions via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-352: Cross-Site Request Forgery (CSRF)
Reaching this weakness in Request For Quote < 1.3 takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.
An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For Request For Quote the fix is 1.3: builds < 1.3 are affected, anything from 1.3 onward is not.
Remediation
Update to version 1.3, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Request For Quote: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Request For Quote 1.3 closes this, and updating the plugin is the step that ends it.
