At a glance

CVE-2024-43280 is a medium-severity URL Redirection to Untrusted Site ('Open Redirect') vulnerability in the Salon Booking System WordPress plugin, affecting versions <= 10.8.1. It carries a CVSS score of 6.1 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 10.9; sites on affected versions should update now. Disclosed August 2024, reported by Le Ngoc Anh.

Vulnerability Overview

The Salon Booking System plugin for WordPress is vulnerable to Open Redirect in all versions up to, and including, 10.8.1. This is due to insufficient validation on the redirect url supplied. This makes it possible for unauthenticated attackers to redirect users to potentially malicious sites if they can successfully trick them into performing an action.

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.

CWE-601: URL Redirection to Untrusted Site ('Open Redirect')

Reaching this weakness in Salon Booking System <= 10.8.1 takes no account at all. An open redirect is a page that takes a destination from the request and sends the browser there without checking that the destination belongs to the site.

A link that starts on a trusted domain finishes on an attacker's, which is what makes phishing and consent-screen abuse credible to the person clicking it. For Salon Booking System the fix is 10.9: builds <= 10.8.1 are affected, anything from 10.9 onward is not.

Remediation

Update to version 10.9, or a newer patched version

How does WordSec protect against this?

Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Salon Booking System 10.9 closes this, and updating the plugin is the step that ends it.
