    Just published another remote code execution chain I exploited recently. I also wrote about how organizations can stop these attacks at the development stage - the key is convention over configuration.

    Someone dropped a PHP zero-day on GitHub. Talked to the PHP team last night. Bug requires local foothold to exploit, so not usable for remote attacks. Also, this is the second exploit for this "disable_functions bypass" in the last few months.

    .Net being open-source makes tracking these things cool. I just hope GitHub adds code navigation support for .net code soon as well. credit for the bug goes to of course.
