Lab Description

This lab offers a practical exploration of vulnerabilities in the IceWarp mail server, specifically targeting CVE-2020-8512, a reflective cross-site scripting (XSS) flaw. You'll begin by working in a test environment designed to replicate real-world scenarios, allowing safe experimentation with live vulnerability mechanics.

The exercise walks you through identifying how IceWarp processes input, leading to the discovery of improperly sanitized fields vulnerable to XSS attacks. You’ll then exploit these flaws to understand the potential damage such vulnerabilities can cause, including session hijacking and data theft. Beyond exploitation, the lab introduces mitigation strategies that can be applied to reduce the risk of XSS in production environments. This includes secure input validation, output encoding, and content security policies. The goal is to ensure that you walk away with both offensive and defensive knowledge related to web application security.

By engaging with this lab, you'll deepen your understanding of how cross-site scripting works, why it continues to be a critical threat vector, and what developers and security teams can do to address it.
