Vulnerability Overview

An issue was discovered in the PageLayer plugin before 1.1.2 for WordPress. Nearly all of the AJAX action endpoints lacked permission checks, allowing these actions to be executed by anyone authenticated on the site. This happened because nonces were used as a means of authorization, but a nonce was present in a publicly viewable page. The greatest impact was the pagelayer_save_content function that allowed pages to be modified and allowed XSS to occur.

Technical Analysis

REMEDIATION: Update to version 1.1.2, or a newer patched version --- IDENTIFIER: CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
