Any help is highly appreciated, 🙏 check TODO!. uxss-db 🔪 The non-persistent (or reflected) cross-site scripting vulnerability is by far the most basic type of web vulnerability. These holes show up when the data provided by a web client, most commonly in HTTP query parameters (e.g. HTML form submission), is used immediately by server-side scripts to parse and display a page of results for and to that user, without properly sanitizing the content. In certain apps, this UXSS can be used to access privileged APIs, which can lead to other vulnerabilities. Some APIs may allow Remote Code Execution (RCE) with the privileges of the application.

However, in very limited cases, this UXSS could be used to access privileged application-exposed APIs, and in very rare cases, use those APIs perform scoped Remote Code Execution (RCE). No widely-used production app has been identified as vulnerable to scoped RCE via this UXSS, but I have verified this as technically possible. KNOXSS is an unique online tool for detection and Proof of Concept (PoC) of Cross-Site Scripting (XSS) web vulnerabilities.

The same can be done with Paypal, your favorite bank account, or 90% of the sites in the planet (the ones that use iframes). From now on, every time we find a way to access a domainless blank (generally about:blank, but we can use others as well), we will have a UXSS. We are working with DevTools because I want to make sure that we completely understand what we are doing, but of course we don’t need it! Stand-Alone PoC. No DevTools Required.

A proof-of-concept (PoC) exploit for the vulnerability, tested on Internet Explorer 11 running on Windows 7, was published by Leo over the weekend. The PoC shows how an external domain can alter the content of a website. In the demonstration, the text “Hacked by Deusen” is injected into the website of The Daily Mail.
