You are absolutley not safe I would recommend patching. I got 3 false positives off of machines that I tested as well.

What is all the fuss about the webdev vul?



I have an IIS5.0 server SP3 and thought I best check

this out so tried the following to test and exploit my

server



webdevfinder.pl - by SensePost Research

      returns - WebDAV possibly in use

 

OK looks like a problem, so now test exploit using:



webdavx.pl  - by isno () xfocus org

   returns - attempting all the offsets 0-7:

     send buffer...  

      telnet target 7788

      if fail, try other offset(0-7)

    

    All telnet attempts failed to connect!



webdavIIS50.pl by www.infowarfare.dk

  Returns

    IIS 5.0 WebDAV BufferOverflow attack

    but fails to do anything!!



wbr.exe -  ntdll.dll exploit trough WebDAV by kralor[Crpt]

     failed to nc to my listening port!



     Results:

     Checking WebDav on 'xxxx' ... FOUND

     exploiting ntdll.dll through WebDav [ret: 0x00100010]

     Connecting... CONNECTED

     Sending evil request... SENT

     Server seems to be patched.

     data: HTTP/1.1 500 Internal Server Failure

     Server: Micr╠╠ñ²↕



     Hey this server is not patched!



Ok all the above failed, so I am safe?



Next step was to build a Win2k SP 1 - default install

IIS5.0 and repeat all the above.



Guess what all failed, so even with SP1 and SP3 -

straight out of the box I was not vuln to this WebDev

exploit



So what is all of the fuss about?

During the testing both Web servers still ran and never

when down.



Cheers peter
