#
# 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/
#
