The University of Southern California (https://www.usc.edu/ ) had a major flaw in its website. I identified this flaw as the Tiki Wiki CMS Calendar 14.2 Remote Code Execution (EDB-ID: 39965) vulnerability. I was able to exploit the RCE vulnerability in the calendar & gain a shell onto their website. I decided to publicly to put the shell on their website for sale, in which it was sold for an amount I do not wish to disclose.”]
