  # Exploit Title: Battle.Net 1.5.0.7963 Local Privilege Escalation # Date: 11/09/2016 # Exploit Author: Tulpa # Contact: tulpa@tulpa-security.com # Author website: www.tulpa-security.com # Vendor Homepage: www.battle.net # Software Link: https://eu.battle.net/account/download/ # Version: Version 1.5.0.7963 # Tested on: Windows 10 Professional x64 and Windows XP SP3 x86     1. Description:   Battle.Net installs by default to "C:\Program Files (x86)\Battle.Net" with weak folder permissions granting any built-in user account with full permission to the contents of   the directory and it's subfolders. This allows an attacker opportunity for their own code execution under any other user running the application. This is not limited to just   the Battle.Net directory, but also to any of Blizzards game installation folders as installed by Battle.Net.   2.
