+title: Open Redirect in noVNC proxy
+
+description: >
+  Swe Aung, Shahaan Ayyub, and Salman Khan with the Monash University Cyber
+  Security team reported a vulnerability affecting Nova's noVNC proxying
+  implementation which exposed access to a well-known redirect behavior in the
+  Python standard library's http.server.SimpleHTTPRequestHandler and thus
+  noVNC's WebSockifyRequestHandler which uses it. By convincing a user to
+  follow a specially-crafted novncproxy URL, the user could be redirected to an
+  unrelated site under control of the attacker in an attempt to convince them
+  to divulge credentials or other sensitive data. All Nova deployments with
+  novncproxy enabled are affected.
