Directory Traversal

io.vertx:vertx-web is a HTTP web applications for Vert.x.

Affected versions of this package are vulnerable to Directory Traversal when running Vertx web applications that serve files using StaticHandle. If the mount point is a wildcard (*) then an attacker can exfiltrate any class path resource.
