Vulnserver: Buffer overflow in HTER command with a small obstacle

9 September 2019 at 00:00

We are back from a vacation and it’s time to keep going with the Vulnserver series of posts. In this post we are going to exploit the crash found in the HTER command of Vulnserver. And important note to make before starting is that this post is going to be shorter than the previous one since I’m going to skip the steps that we have already seen.

Vulnserver: Egghunter in GTER and KSTET after buffer overflow

7 November 2019 at 00:00

In this post we are going to exploit a buffer overflow in both commands, GTER and KSTET, since the exploits are very similar I’m covering them both in the same post. We are going to use a new technique called an egghunter that will allow us to exploit targets that don’t give us enough length in the initial payload to put our shellcode.
