Abstract:
=========
Vulnerability Laboratory Research Team discovered multiple persistent web vulnerabilities in Squirrelcarts Shopping 
Content Management System v3.3.4.


Report-Timeline:

Status:

Published


Exploitation-Technique:
=======================
Remote


Severity:
=========
Medium


Details:
========
Multiple persistent input validation vulnerabilities are detected in Squirrelcart Shopping v3.3.4 Content Management 
System.
The bugs allow remote attackers to implement/inject malicious script code on the application side (persistent). 
Successful exploitation of the vulnerability can lead to session hijacking (manager/admin) or stable (persistent) 
context manipulation. Exploitation requires low user inter action & privileged user account. The persistent 
vulnerabilities 
are located in the Discount Image > Document Edit Name module exception handling & the Location Hours of Operations day 
listing.
When a customer includes the malicious script code to the profile configuration settings the code is getting executed 
out
of the web application context when an administrator is processing to watch the listings.

Vulnerable Module(s):
                                [+] Group > Add Group or Customer > Detail > Image > Discount Image > Document Edit Name
                                [+] Location > Warehouse > Listing > Hours of Operation

                                ../2.png


Proof of Concept:
=================
The persistent input validation vulnerabilities can be exploited by remote attacker or privileged user account with low
required user inter action. For demonstration or reproduce ...

Location - Warehouse - Listing - Hours of Operation

Review: Hours of Operation 
(https://127.0.0.1:80/squirrelcart/index.php?edit_records=x&selected_record_number=x&table=Locations)

<td class="field_td" style=""><div style="float: left;"><input id="Hours_Day_1" descriptor="Day(s)" 
name="data[Locations][1][Hours_Day_1]" value=""><[PERSISTENT SCRIPT CODE];) <" style="width: 150px;" type="text">
</div>
