DroopyCTF Walkthrough
Preparation:
Download the DroopyCTF virtual machine from the following website:
https://www.vulnhub.com/entry/droopy-v02,143/
1. Scan the network to find the IP address of the DroopyCTF server.
netdiscover -r 10.0.0.0/24
2. Scan the DroopyCTF server using Nmap to find some potential vulnerabilities.
TCP Scan 1:
nmap -Pn -sS --stats-every 3m --max-retries 1 --max-scan-delay 20 --defeat-rst-ratelimit -T4 -p1-65535 -oN /root/Delete/tcp1.txt 10.0.0.30
TCP Scan 2:
nmap -nvv -Pn- -sSV -p 80 --version-intensity 9 -A -oN /root/Delete/tcp2.txt 10.0.0.30
UDP Scan:
map -Pn --top-ports 1000 -sU --stats-every 3m --max-retries 1 -T3 -oN /root/Delete/udp.txt 10.0.0.30
3. Browse the website(http://10.0.0.30/) through Firefox. Nothing valuable find in the source page.
Browse the website(http://10.0.0.30/robots.txt) through Firefox.
Browse the website(http://10.0.0.30/CHANGELOG.txt) through Firefox and try to find some vulnerabilities.
