LetsDefend - Shellshock Attack#
Created: 12/01/2024 12:13 Last Updated: 16/01/2024 14:15
Shellshock Attack
Log file: https://files-ld.s3.us-east-2.amazonaws.com/shellshock.zip Pass: 321
Note: pcap file found public resources.
Start Investigation#
Let’s open this pcap file in Wireshark
At first sight, There were some SSH,TCP,HTTP and ICMP packets in this pcap file
I followed HTTP/TCP stream to find out about some basic server information
And jackpot! We also found all the answers including payload that trying to exploit shellshock vulnerability.
What is the server operating system?
1ubuntuWhat is the application server and version running on the target system?
1Apache/2.2.22What is the exact command that the attacker wants to run on the target server?
1/bin/ping -c1 10.246.50.2Summary#
This pcap file captured a moment where system 10.246.50.2 tried to use shellshock vulnerability to exploit an Apache server hosted on Ubuntu system (10.246.50.6)
Badge Acquired
