System Network Connections Discovery is a part of the post-exploitation phase and deals with identifying network connections made to/from the compromised system
In this lab, we are given access to a Kali machine. A target machine is present on the same network. This target machine is vulnerable and can be exploited using the following information. Use this information to get a shell on the target machine and complete the mission!
- Vulnerability: Arbitrary File Upload vulnerability exists on WolfCMS web application.
- Vulnerability: setuid and setgid bit are set on bash binary, therefore the bash binary can be leveraged to escalate to root user.
- Identify the total number of established connections.
- Identify the IP address of the client who has connected to the target machine via SSH.
- Identify the hostname of the client who has connected to the target machine over UDP protocol.
- Identify the services which are listening on TCP ports of the target machine.
- System Network Connections Discovery (https://attack.mitre.org/techniques/T1049/)
- This lab is dedicated to you! No other users are on this network :)
- Once you start the lab, you will have access to a root terminal of a Kali instance
- Your Kali has an interface with IP address 192.X.Y.2. Run "ip addr" to know the values of X and Y.
- The target server should be located at the IP address 192.X.Y.3.
- Do not attack the gateway located at IP address 192.X.Y.1
|1.||How many clients are connected to the target machine (Excluding HTTP Connections)?||
|2.||What is the IP address of the client who connected to target machine via SSH?||
|3.||What is the hostname of the client who established a connection over UDP protocol?||
The following activities are strictly prohibited on this website unless otherwise explicitly stated as allowed in the mission statement:
- Using automated scanners
- Using brute force attacks
- Denial of Service attacks
- Attacking other student machines in challenges where you might achieve a shell on the vulnerable system
- Attacking the lab infrastructure
Users violating the above will be either temporarily or permanently banned from the website.
If you are unsure about an activity, then please contact support to confirm that it is allowed on our website.
Technical Support for this Lab:
There is a reason we provide unlimited lab time: you can take as much time as you need to solve a lab. However, we realize that sometimes hints might be necessary to keep you motivated!
We currently provide technical support limited to:
- Giving hints for a lab exercise
- In rare circumstances, if you have totally given up (NO!!!) then tell you how to solve it. This will be limited to sharing the solution video or lab report
- A lab exercise fails to load or has errors in it
If you need technical support, please email firstname.lastname@example.org clearly mention the name and link of the lab exercise and other essential details. The more descriptive you are, the faster we can help you. We will get back to you within 24 hours or less.
For adminitrative queries, billing, enterprise accounts etc. please email email@example.com
