At a glance

CVE-2022-0616 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Booking for Appointments and Events Calendar WordPress plugin, affecting versions <= 1.0.46. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.0.47; sites on affected versions should update now. Disclosed February 2022, reported by Muhamad Hidayat.

Vulnerability Overview

The Amelia WordPress plugin before 1.0.47 does not have CSRF check in place when deleting customers, which could allow attackers to make a logged in admin delete arbitrary customers via a CSRF attack

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-352: Cross-Site Request Forgery (CSRF)

Reaching this weakness in Booking for Appointments and Events Calendar <= 1.0.46 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 Booking for Appointments and Events Calendar the fix is 1.0.47: builds <= 1.0.46 are affected, anything from 1.0.47 onward is not.

Remediation

Update to version 1.0.47, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Booking for Appointments and Events Calendar: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Booking for Appointments and Events Calendar 1.0.47 closes this, and updating the plugin is the step that ends it.
