At a glance

CVE-2023-35047 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the All Bootstrap Blocks WordPress plugin, affecting versions <= 1.3.6. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.3.7; sites on affected versions should update now. Disclosed June 2023, reported by LEE SE HYOUNG.

Vulnerability Overview

The All Bootstrap Blocks plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.3.6. This is due to missing nonce validation on the reset() function. This makes it possible for unauthenticated attackers to reset the plugin's settings 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, and no interaction from a victim user.

CWE-352: Cross-Site Request Forgery (CSRF)

All Bootstrap Blocks <= 1.3.6 carries this weakness at reset(), and reaching it 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 All Bootstrap Blocks the fix is 1.3.7: builds <= 1.3.6 are affected, anything from 1.3.7 onward is not.

Remediation

Update to version 1.3.7, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to All Bootstrap Blocks: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: All Bootstrap Blocks 1.3.7 closes this, and updating the plugin is the step that ends it.
