Lab: DOM-based open redirection
Summary: This PortSwigger lab contains a DOM-based open-redirection vulnerability in the url parameter of a blog post page's "Back to Blog" link, which lets an attacker change where that link sends the user. Solving the lab requires constructing a URL with the lab ID and exploit server ID to redirect the victim to the exploit server.
What's compelling: A link that looks like it returns to your own blog can be rewritten through a client-side parameter to send users to an attacker-controlled server, and the source gives no server-side check that would catch it.
