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


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


Technical Details & Description:
================================
An application-side input validation web vulnerability has been discovered in the official Lithium Forum online service web-application.
The vulnerability allows remote attacker to inject own malicious script codes to the application-side of the vulnerable module/function.

The vulnerability is located at the previewImages value of the file upload module. Remote attackers are able to inject malicious script codes 
to the file upload module POST method request to compromise the `Community > Albums (unmoderated%3Amedia)` module. The attack vector of the 
vulnerability is located on the application-side of the service and the request method to inject is POST. The execution point is the vulnerable 
Albums listing service. Due to the testings and research we figured out that several high class vendors using the commercial lithium web-application 
like ebay, vodafone, paypal, microsoft, skype and sony.

The security risk of the application-side web vulnerability is estimated as medium with a cvss (common vulnerability scoring system) count of 4.7. 
Exploitation of the persistent web vulnerability requires a low privilege web application user account and low user interaction (click or forward). 
Successful exploitation of the vulnerability results in session hijacking, persistent phishing, persistent external redirects, persistent load of 
malicious script codes or persistent web module context manipulation.

Affected Request Method(s):
								[+] POST

Vulnerable Module(s):
								[+] Lithium Forum - Community > File Upload (Image)

Vulnerable Parameter(s):
								[+] previewImages

Affected Service(s):
								[+] Lithium Forum - Community > Albums (unmoderated%3Amedia)


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

Manual steps to reproduce the vulnerability ...
1. Register an lithium forum account and login to the web-application 
2. Open link  /t5/media/gallerypage
3. click add images
4. Upload image with name "><img src="x" onerror=alert(document.cookie)>.png 
5. Click select an album and save 
6. The first execution of the payload occurs in the comment delete function the second execution occurs in the album to authorize listing
7. Successful reproduce of the vulnerability!

Solution - Fix & Patch:
=======================
Parse and encode the title name of the albums and files to prevent persistent script code execution through the api. 
Restrict the input and disallow usage of special chars as album name value.


Security Risk:
==============
The security risk of the persistent input validation web vulnerability in the album value is estimated as medium. (CVSS 4.6)
