At a glance

CVE-2024-3022 is a high-severity Unrestricted Upload of File with Dangerous Type vulnerability in the Appointment Booking Calendar Plugin and Scheduling Plugin WordPress plugin, affecting versions <= 1.0.87. It carries a CVSS score of 7.2 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Admin level or above. The issue is fixed in version 1.0.88; sites on affected versions should update now. Disclosed April 2024, reported by Dian Sun.

Vulnerability Overview

The BookingPress plugin for WordPress is vulnerable to arbitrary file uploads due to insufficient filename validation in the 'bookingpress_process_upload' function in all versions up to, and including 1.0.87. This allows an authenticated attacker with administrator-level capabilities or higher to upload arbitrary files on the affected site's server, enabling remote code execution.

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. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-434: Unrestricted Upload of File with Dangerous Type

Appointment Booking Calendar Plugin and Scheduling Plugin <= 1.0.87 carries this weakness at bookingpress_process_upload, and reaching it takes an account at Admin level or above. An unrestricted file upload lets a caller store a file whose type or destination the application does not properly constrain.

If an uploaded file lands anywhere the server will execute, the flaw becomes remote code execution and the site should be treated as fully compromised. For Appointment Booking Calendar Plugin and Scheduling Plugin the fix is 1.0.88: builds <= 1.0.87 are affected, anything from 1.0.88 onward is not.

Remediation

Update to version 1.0.88, or a newer patched version

How does WordSec protect against this?

An attacker needs Admin access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: Appointment Booking Calendar Plugin and Scheduling Plugin 1.0.88 closes this, and updating the plugin is the step that ends it.
