CVE-2023-4213 (GCVE-0-2023-4213)

Vulnerability from cvelistv5 – Published: 2023-09-13 02:54 – Updated: 2026-04-08 16:59

Title
Simplr Registration Form Plus+ <= 2.4.5 - Authenticated (Subscriber+) Insecure Direct Object Reference to Arbitrary User Password Change
Summary
The Simplr Registration Form Plus+ plugin for WordPress is vulnerable to Insecure Direct Object References in versions up to, and including, 2.4.5. This is due to the plugin providing user-controlled access to objects, letting a user bypass authorization and access system resources. This makes it possible for authenticated attackers with subscriber-level permissions or above to change user passwords and potentially take over administrator accounts.

Mitigation
Architecture and Design

For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.

Mitigation
Architecture and Design Implementation

Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.

Mitigation
Architecture and Design

Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.
