# Vulnerability Assesment

1.    FTP Login Anonymous allowed
2.    OpenSSH Denial of Service
3.    Directory Listing

# Exploitation

First, I'm interesting with FTP login but I dont't get anything in the ftp.

Second, I have try on openSSH with vulnerable DOS. Try using this exploit and the ssh service temporary down. /pentest/exploits/exploitdb# platforms/multiple/dos/2444.sh

Third, I'm trying to directory listing on http service. this part separated into 3 step :

Create userlisting from available info in their web site.
Create file listing for common user in linux syste,
Combination userlisting and filelisting with dirb, dirb available in backtrack.

root@bt:/pentest/web/dirb# ./dirb http://192.168.2.101/ /root/Slax2.100/credential.txt,/root/Slax2.100/filelist.txt -w -l

Dirb usage:

From the dirb, you can see ~pirrip/.ssh/ listing. Then open it from your browser and download the id_rsa and id_rsa.pub. Two files is ssh key authentication. Now connect to the machine target with ssh.

# ssh -i id_rsa pirrip@192.168.2.100

Well, we have connected into target machine. But we don't know what is the password of pirrip.

Finally I'm using grep to find string with password.

# grep -r "Password" /

For the long time, I got the password of pirrip -> 0l1v3rtw1st
