Mischief after patch

So after 4-5 hours of thinking I can’t pass the second login page. I have 2 creds none of them work for second login page. I tried all sorts of word mangling,used john the ripper’s word mangling feature(also rsmangler’s). Tried brute forcing but didn’t work. Tried reading snmp output but nothing more interesting. Scanned all TCP/UDP ports. Tried SQLi. Can’t think of any other way. One little hint will be appreciated. I even thought that this box is somehow related to “Thor” movie. But can’t find a connection.
