Vulnerability Overview

The Login with phone number plugin for WordPress is vulnerable to Reflected Cross-Site Scripting in versions up to, and including, 1.4.1 via the 'ID' parameter of the 'lwp_forgot_password' AJAX action. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

Technical Analysis

CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

OTP Login With Phone Number, OTP Verification < 1.4.2 carries this weakness at lwp_forgot_password, and reaching it takes a caller who can reach the endpoint. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.

Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For OTP Login With Phone Number, OTP Verification the fix is 1.4.2: builds < 1.4.2 are affected, anything from 1.4.2 onward is not.

Remediation

Update to version 1.4.2, or a newer patched version
