At a glance

CVE-2023-37887 is a medium-severity Missing Authorization vulnerability in the School Management System WordPress plugin, affecting versions <= 2.2.3. It carries a CVSS score of 5.4 (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 2.2.4; sites on affected versions should update now. Disclosed July 2023, reported by Fariq Fadillah Gusti Insani (fariqfgi).

Vulnerability Overview

The WPSchoolPress plugin for WordPress is vulnerable to unauthorized use of functionality due to a missing capability check on several functions such as wpsp_AddStudent(), wpsp_DeleteTeacher(), wpsp_UpdateStudent(), wpsp_DeleteStudent and more in versions up to, and including, 2.2.3. This makes it possible for authenticated attackers, with student-level access and above, modify student and teacher accounts.

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

School Management System <= 2.2.3 carries this weakness at wpsp_AddStudent(), and reaching it 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 School Management System the fix is 2.2.4: builds <= 2.2.3 are affected, anything from 2.2.4 onward is not.

Remediation

Update to version 2.2.4, 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: School Management System 2.2.4 closes this, and updating the plugin is the step that ends it.
