Re: privelege escalation with .bat files

If the .bat file could be executed, services like telnet etc can be startet,
or users maybe added.

On desktop systems (or stuff like that) were the user isn’t allowed to use
the Dos-shell but writing .bat files it is easy to execute system cmds.

Betreff: privelege escalation with .bat files

Hi.  I'm pen-testing an IIS 5.0 server that is insecurely set up to allow 
write-access to it as a web folder.  However, its also set up to deny 
copying (or renaming to) of the following file extensions .asp, .com, .cmd, 
.exe, and .dll. Interestingly, it does allow .bat files to be written onto 
the server.  Is there a way to escalate privelleges (and possibly get a 
command prompt) through a .bat file?  Thank you,

--ben
