# Exploit Title: Socusoft Photo 2 Video Converter v8.0.0 Local Buffer Overflow (Free and Professional variants) 
# Date: 01/12/2017
# Exploit Author: Jason Magic (ret2eax)
# Vendor Homepage: www.socusoft.com
# Version: 8.0.0
# Tested on: Windows Server 2008 R2

# Socusoft's Photo 2 Video Converter v8.0.0 (Free and Professional variants) 
# contains a local buffer overflow condition in the pdmlog.dll library. 
# Exploitation can result in register rewrites to control program execution 
# flow, therefore, resulting in the ability to execute arbitrary shellcode leading 
# to complete system compromise.

# Import generated .reg prior to restarting the executable within a debugger

#  The following PUSH ESP, RETN instruction sequence addresses are suitable to 
#  redirect program execution:
	
#  DVDPhotoData.dll:

#	0x10002352 push esp; ret
#	0x10013945 push esp; retn 0x0004
#	0x1004cb83 push esp; retn 0x0008
#	0x1004cbb8 push esp; retn 0x0008
#	0x1004cc11 push esp; retn 0x0008
