We are solving Crossfit2, a 50-point OpenBSD machine on HackTheBox.
We are solving Cereal, a 40-point machine on HackTheBox. For user, we will exploit a pretty tricky deserialization vulnerability in a .NET web app. For root, we exploit SeImpersonate.
Solving Crossfit, a 50-point Linux machine on HackTheBox which involves a lot of cross-site scripting, a command-injection, and finally some light reversing.
Bankrobber is a 50-point machine on hackthebox that involves exploiting a cross site scripting vulnerability to gain access to an admin account, using a command injection to get a user shell and exploiting a simple buffer overflow to become system.
