This is an alternative (and complete) exploit for CVE-2019-8605. I have only implemented the exploit and do not claim any rights for discovering and/or publishing the vulnerability. The actual exploit code is in “SockPuppet3.cpp”, other files are either helpers or documentation. This exploit [1] has already been verified in production several times [2] [3], however, I can assist in additional verification if required.
