Well I'll include it to this post then
I just got it compiled.. ;x

Get Cygwin1.dll iif you don't have it.. ;x it needs it

local exploit right??

yes

local? you can also send the job file to someone else that will automaticly run it and bind a shell to the specified port.. so which means remote and local.. the other one.. the notepad.exe executing one is local..

Why shouldn't you need a local bindport ?

hmm didnt work for me, yet. tried 6 servers without shell...

Serhat

Aug 1 2004, 03:46 PM

I heard about someone getting 3/4 shells with it.. though the computer needs to meet some requirments... like running the Task Sheduler service ( which I don't!

) etc..
also I can't confirm whether it works 100% also.. cause I didn't tested it yet.. just compiled the source code for you guys =)

Serhat

and how should i send this jobfile to a machine

with this exploit i need a box . if i sit in front of the the box or i have a remote shell is not important

just use the way you like.. for example you can send it to somebody's shares if he has enabled it.. meaning it will bind a port when the directory is beeing viewed.. dunno sure if beeing viewed via the shares executes it aswell..

Hang on a minute ..... When you open the folder to find the .job file to send to someone are you not infecting yourself ?

yes depending on how youve set it up
turn off task scheduler or patch your computer

like nuorder said.. patch your system or turn off Task Scheduler...
someone like you should already be patched I guess.. and for me.. well I am patched and disabled Task Scheduler cause I didn't use it anyway.. though cause of this I can't use the AT command .. which I don't really need anyway ;x
Also the standard port 1027/1028 or something of Task Sheduler is closed cause of it also =)

Well if there is, its probably for another vulnerability (maybe unreleased) because this one needs interaction....
