CVE-2018-11763
Apache HTTP Server HTTP/2 Settings Frame Denial of Service (DoS)
Description
In Apache HTTP Server 2.4.17 to 2.4.34, by sending continuous, large SETTINGS frames a client can occupy a connection, server thread and CPU time without any connection timeout coming to effect. This affects only HTTP/2 connections. A possible mitigation is to not enable the h2 protocol.

DC-3 is another purposely built vulnerable lab with the intent of gaining experience in the world of penetration testing. As with the previous DC releases, this one is designed with beginners in mind, although this time around, there is only one flag, one entry point and no clues at all.
This is a boot2root VM and is a continuation of the Basic Pentesting series. This series is designed to help newcomers to penetration testing develop pentesting skills and have fun exploring part of the offensive side of security. VirtualBox is the recommended platform for this challenge (though it should also work with VMware -- however, I haven’t tested that). This VM is a moderate step up in difficulty from the first entry in this series. If you’ve solved the first entry and have tried a few other beginner-oriented challenges, this VM should be a good next step. Once again, this challenge contains multiple initial exploitation vectors and privilege escalation vulnerabilities. Your goal is to remotely attack the VM, gain root privileges, and read the flag located at /root/flag.txt. Once you’ve finished, try to find other vectors you might have missed! If you’d like to send me a link to your writeup, enjoyed the VM or have questions or feedback, feel free to contact me at: [email protected] If you finished the VM, please also consider posting a writeup! Writeups help you internalize what you worked on and help anyone else who might be struggling or wants to see someone else’s process. There were lots of wonderful writeups for Basic Pentesting: 1, and I look forward to reading the writeups for this challenge.
This is walkthrough of another Boot2Root Vulnhub machine ! This can be a real life scenario if rockies becomes admins. Easy going in round about 15 mins.
Results are limited to the first 15 repositories due to potential performance issues.
