It usually appears, when users input is presented. This attack can be used to impersonate a user, take over control of the session, or even steal API keys.</p> <p>The attack can be executed e.g. when you application injects the request parameter directly into the HTML code of the page returned to the user:</p> <p class="feature-text">https://server.com/confirmation?message=Transaction+Complete</p> <p>what results in:</p> <p class="feature-text"><span>Confirmation: Transaction Complete</span></p> <p>In that case the message can be modified to become a valid Javascript code, e.g.:</p> <p class="feature-text">https://server.com/confirmation?message=<script>dangerous javascript code here</script></p> <p>and it will be executed locally by the user's browser with full access to the user's personal application/browser data:</p> <p class="feature-text"><span>Confirmation: <script>dangerous javascript code here</script></span></p> </div> <a href="/scan-now" class="btn btn--fill"><span>Scan Your Web App Now</span></a> </div> </div> </section> </div> <section class="get-started"> <div class="wrap wrap--inner animate"> <div class="header header--center"> <div class="typo-h2"> <h5>Scan your application<br> for 14 days for free</h5> </div> <p>No credit card is required.
