Vulnerable Application

This module attempts to use john the ripper to decode oracle based password hashes, such as:

  • oracle (<=10) aka des based passwords
  • oracle11 based passwords
  • Oracle 11 and 12c backwards compatibility H field (MD5)
  • oracle12c based passwords

Sources of hashes can be found here: source, source2

For a detailed explanation of Oracle 11/12c formats, see www.trustwave.com.

Oracle 11/12c H field is dynamic_1506 in JtR and added here

Verification Steps

  1. Have at least one user with an oracle, oracle11, or oracle12c password in the database
  2. Start msfconsole
  3. Do: use auxiliary/analyze/jtr_oracle_fast
  4. Do: run
  5. You should hopefully crack a password.

Options

CONFIG

The path to a John config file (JtR option: --config). Default is metasploit-framework/data/john.conf

CUSTOM_WORDLIST

The path to an optional custom wordlist. This file is added to the new wordlist which may include the other USE items like USE_CREDS, and have MUTATE or KORELOGIC applied to it.

DeleteTempFiles

This option will prevent deletion of the wordlist and file containing hashes. This may be useful for running the hashes through john if it wasn't cracked, or for debugging. Default is false.

ITERATION_TIMEOUT

The max-run-time for each iteration of cracking

JOHN_PATH

The absolute path to the John the Ripper executable. Default behavior is to search path for john and john.exe.

KORELOGIC

Apply the KoreLogic rules to Wordlist Mode (slower). Default is false.

MUTATE

Apply common mutations to the Wordlist (SLOW). Mutations are:

  • '@' => 'a'
  • '0' => 'o'
  • '3' => 'e'
  • '$' => 's'
  • '7' => 't'
  • '1' => 'l'
  • '5' => 's'

Default is false.

POT

The path to a John POT file (JtR option: --pot) to use instead. The pot file is the data file which records cracked password hashes. Kali linux's default location is /root/.john/john.pot. Default is ~/.msf4/john.pot.

USE_CREDS

Use existing credential data saved in the database. Default is true.

USE_DB_INFO

Use looted database schema info to seed the wordlist. This includes the Database Name, each Table Name, and each Column Name. If the DB is MSSQL, the Instance Name is also used. Default is true.

USE_DEFAULT_WORDLIST

Use the default metasploit wordlist in metasploit-framework/data/wordlists/password.lst. Default is true.

USE_HOSTNAMES

Seed the wordlist with hostnames from the workspace. Default is true.

USE_ROOT_WORDS

Use the Common Root Words Wordlist in metasploit-framework/data/wordlists/common_roots.txt. Default is true.
