At a glance

CVE-2021-24585 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the Timetable and Event Schedule by MotoPress WordPress plugin, affecting versions <= 2.3.19. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high confidentiality impact). The issue is fixed in version 2.4.0; sites on affected versions should update now. Disclosed August 2021, reported by dc11.

Vulnerability Overview

The Timetable and Event Schedule WordPress plugin before 2.4.0 outputs the Hashed Password, Username and Email Address (along other less sensitive data) of the user related to the Even Head of the Timeslot in the response when requesting the event Timeslot data with a user with the edit_posts capability. Combined with the other Unauthorised Event Timeslot Modification issue (https://wpscan.com/reports/submissions/4699/) where an arbitrary user ID can be set, this could allow low privilege users with the edit_posts capability (such as author) to retrieve sensitive User data by iterating over the user_id

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.

CWE-200: Exposure of Sensitive Information to an Unauthorized Actor

Reaching this weakness in Timetable and Event Schedule by MotoPress <= 2.3.19 takes a caller who can reach the endpoint. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.

The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. For Timetable and Event Schedule by MotoPress the fix is 2.4.0: builds <= 2.3.19 are affected, anything from 2.4.0 onward is not.

Remediation

Update to version 2.4.0, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: Timetable and Event Schedule by MotoPress 2.4.0 closes this, and updating the plugin is the step that ends it.
