Shown Cross Website Scripting (XSS)

A showed cross-site scripting vulnerability on WordPress usually occurs when an input anticipates something particular (like an image upload or text) but allows other inputs, including harmful scripts.

An assailant can then carry out scripts on a site visitor’s web browser.

If the user is an admin then there can be a capacity for the opponent stealing the admin qualifications and taking over the site.

The non-profit Open Web Application Security Project (OWASP) explains this sort of vulnerability:

“Shown attacks are those where the injected script is reflected off the web server, such as in a mistake message, search engine result, or any other reaction that consists of some or all of the input sent to the server as part of the request.

Shown attacks are delivered to victims by means of another route, such as in an e-mail message, or on some other website.

… XSS can trigger a variety of issues for the end user that vary in seriousness from an inconvenience to finish account compromise.”

Since this time the vulnerability has actually not been assigned a seriousness rating.

This is the main description of the vulnerability by the U.S. Federal Government National Vulnerability Database:

“The Booster for WooCommerce WordPress plugin before 5.6.3, Booster Plus for WooCommerce WordPress plugin before 6.0.0, Booster Elite for WooCommerce WordPress plugin prior to 6.0.0 do not escape some URLs and parameters before outputting them back in attributes, leading to Shown Cross-Site Scripting.”

What that suggests is that the vulnerability includes a failure to “get away some URLs,” which suggests to encode them in special characters (called ASCII).

Escaping URLs implies encoding URLs in an expected format. So if a URL with a blank area is come across a site may encoded that URL using the ASCII characters “%20” to represent the encoded blank area.

It’s this failure to properly encode URLs which allows an assailant to input something else, most likely a destructive script although it might be something else like a redirection to malicious website.
