Introduction:
=============
Popcorn adds interactivity and context to online video, pulling the rest
of the web right into the action in real time.
Popcorn lets users link social media, news feeds, data visualizations
and other content directly to moving images.
The result is a new form of multimedia storytelling that lives and
breathes more like the web itself: interactive, social,
and unique each time. Popcorn is the result of ongoing collaboration
between filmmakers, developers and webmakers. Together
we explore how modern browser technologies like HTML5 can reshape moving
images online.

Popcorn Maker makes it easy to enhance, remix and share web video. Use
your web browser to combine video and audio
with content from the rest of the web — from text, links and maps to
pictures and live feeds.

Abstract:
=========
The Vulnerability Laboratory Research Team discovered multiple
persistent web vulnerabilities in the Mozilla Popcorn Maker (Webmaker)
Application.

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

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


Details:
========
Multiple persistent input validation web vulnerabilities are detected in
the official Mozilla Popcorn Maker (WebMaker) Web Application.
The vulnerability allows an attacker to inject own malicious script code
in the vulnerable module on application side (persistent).

The persistent input validation vulnerabilities are located in the
events und layer modules when processing to add `Text`, `Link URL`,
`Image URL`, `video-container name` with malicious persistent script
code (js/html). The script code will be executed when the website
is processing to load the malicious manipulated web context of the input
ago.

Exploitation of the vulnerabilities requires no privileged application
user account but low or medium required user interaction.
Successful exploitation results in persistent session hijacking of
mozilla accounts, persistent phishing, persistent external malware loads
or redirects and persistent module web context manipulation.

Vulnerable Service(s):
[+] Mozilla Corp - Popcorn Maker (Webmaker.org - Mozilla Labs)

Vulnerable Module(s):
[+] Events
[+] Layer

Vulnerable Parameter(s):
[+] Text
[+] Link URL
[+] Image URL
[+] Video Container Name

Affected Section(s):
[+] Index Basic - Listing


Proof of Concept:
=================
The persistent input validation web vulnerabilities can be exploited by
remote attackers without privilege application user account
with low or medium required user interaction. For demonstration or
reproduce ...

Solution:
=========
Restrict the input fields with a secure char filter and parse the input
and output listing in the application.


Risk:
=====
The security risk of the persistent input validation web vulnerabilities
are estimated as medium.
