Vulnerability Overview

The Salon Booking System – Appointment Booking for Salons, Barbershops & Spas plugin for WordPress is vulnerable to unauthorized access due to an insufficient capability check on a function in all versions up to, and including, 10.31.8. This makes it possible for unauthenticated attackers to perform an unauthorized 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, and no interaction from a victim user.

CWE-287: Improper Authentication

Reaching this weakness in Salon Booking System <= 10.31.8 takes a caller who can reach the endpoint. Improper authentication means the mechanism that proves who a caller is can be satisfied without the secret it was supposed to require.

An attacker authenticates as another user — administrators included — without ever knowing a password, so password policies and login rate limits never come into play. For Salon Booking System the fix is 10.31.9: builds <= 10.31.8 are affected, anything from 10.31.9 onward is not.

Remediation

Update to version 10.31.9, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Salon Booking System 10.31.9 closes this, and updating the plugin is the step that ends it.
