Hi everyone. This is my solution for LAMP security CTF4. This CTF is very easy, you can download it from Vulnhub.com or play online on root-me.org. I did it on root-me, therefore my target was ctf07.root-me.org.
Ok let’s start, i ran nmap to see which services were open (usually I run a second scan with “-p 1-65535” parameter to identify all the ports).
Syrion:~ syrion$ sudo nmap -sT -sV -O ctf07.root-me.org

Nmap scan report for ctf07.root-me.org (18.104.22.168)
Host is up (0.040s latency).

PORT STATE SERVICE VERSION

Device type: general purpose|WAP
Running (JUST GUESSING): OpenBSD 4.X (88%), Apple embedded (87%), FreeBSD 6.X (87%)
OS CPE: cpe:/o:openbsd:openbsd:4.0 cpe:/h:apple:airport_extreme cpe:/o:freebsd:freebsd:6.2
Aggressive OS guesses: OpenBSD 4.0 (88%), Apple AirPort Extreme WAP (87%), FreeBSD 6.2-RELEASE (87%), FreeBSD 6.3-RELEASE (87%), OpenBSD 4.3 (87%)
No exact OS matches for host (test conditions non-ideal).
At this point I used netcat to verify the services on the three open ports. As excepted:
- SSH on 22
- SENDMAIL on 25
- HTTP on 80
