At a glance
CVE-2024-3602 is a medium-severity Missing Authorization vulnerability in the Promolayer WordPress plugin, affecting versions <= 1.1.0. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). The root cause is a missing authorization check on a reachable function. The issue is fixed in version 1.1.1; sites on affected versions should update now. Disclosed June 2024, reported by Lucio Sá.
Vulnerability Overview
The Pop ups, Exit intent popups, email popups, banners, bars, countdowns and cart savers – Promolayer plugin for WordPress is vulnerable to unauthorized plugin settings update due to a missing capability check on the disconnect_promolayer function in all versions up to, and including, 1.1.0. This makes it possible for authenticated attackers, with subscriber access or higher, to remove the Promolayer connection.
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 interaction from a victim user.
CWE-862: Missing Authorization
Reaching this weakness in Promolayer <= 1.1.0 takes a caller who can reach the endpoint. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.
Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Promolayer the fix is 1.1.1: builds <= 1.1.0 are affected, anything from 1.1.1 onward is not.
Remediation
Update to version 1.1.1, 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: Promolayer 1.1.1 closes this, and updating the plugin is the step that ends it.
