Checks if a JBoss target is vulnerable to jmx console authentication bypass.
|
|
|
|
It works by checking if the target paths require authentication or redirect to a login page that could be
|
|
bypassed via a HEAD request. RFC 2616 specifies that the HEAD request should be treated exactly like GET but
|
|
with no returned response body. The script also detects if the URL does not require authentication at all.
|
|
