"curl's websocket code did not update the 32 bit mask pattern for each
new  outgoing frame as the specification says. Instead it used a fixed
mask that persisted and was used throughout the entire connection.  A
predictable mask pattern allows for a malicious server to induce
traffic between the two communicating parties that could be
interpreted by an involved proxy (configured or transparent) as
genuine, real, HTTP traffic with content and thereby poison its cache.
That cached poisoned content could then be served to all users of that
proxy.

This plugin only works with Tenable.ot.
