Exploit Source

#!/usr/bin/python

# Exploit Title: CyberLink Multiple Products File Project Handling Stack Buffer Overflow POC

# by: modpr0be[at]spentera[dot]com (@modpr0be)

# Platform: Windows

# Tested on: Windows XP SP3, Windows 7 SP1 with:

# CyberLink Power2Go 7 (build 196)

# CyberLink Power2Go 8 (build 1031)

# CyberLink WaveEditor 2.0 (build 2204)

# Software Link: http://www.cyberlink.com/downloads/trials/index_en_US.html

# CVE : -

### Software Description

# CyberLink Power2Go is all-media disc burning software.

# Copy all your media to any disc with Power2Go 8! With new System Recovery tools

# and over 5000 free DVD menus to choose from on DirectorZone.com, Power2Go 8 not

# only burns everything but allows you to create pro-like DVDs, rip CDs and

# safeguard valuable data.

# CyberLink Wave Editor will help user to convert audio format when producing, editing,

# or creating backups for some audios or videos. This additional tools is also included

# since PowerDirector 9 to PowerDirector 10, and now included on Power2Go 8.

### Vulnerability Details

# Most of CyberLink products contain built-in project file with their own format and

# extension. This file usually contains our recently modified project or work.

# Most of this filetypes contain this section:

# <File src=

# <File name=

# Generally, those sections will be filled with source path or filename.

# both products will lead us to command execution because the address of

# SE Handler is overwritten with 0x00410041.

# Notes:

# I cannot find any good return address for WaveEditor, if you can make it

# through the hard way, kudos!!
