Launch PDF Action Mega Abuse !PATCH!

@DidierStevens has released a way to partially “control” the message showed by Adobe Reader when it launches an application from inside a pdf file with the PDFAction “/Launch”. Check it out here

I think it’s about time to start calling the application Launching capability of Adobe (and friends) a VULNERABILITY.

Here you have a python script for PATCHING the affected dll and cripple the Launch Action.

#Megapatch for Didier Launch action abuse

version="9.0"
path = "C:\\Program Files\\Adobe\\Adobe Reader %s\\Reader\\"%version
#path = "./"

data = file(path+"AcroRd32.dll","rb").read()
file(path+"AcroRd32.dll.bak","wb").write(data)
while data.find("Launch")!=-1:
	data = data.replace("Launch","Felipe")
file(path+"AcroRd32.dll","wb").write(data)

I tested it in W7 / Adobe Reader 9.3 but it should work for every version/OS/Arch mixture. In some OS you may experience some trouble replacing the dll.

(((( An untested improvement… s/Felipe/######/g ))))
