hello,
(sorry for my bad english but i am from germany)

I have lost the root password to my virtual-rootserver.
The Server is using confixx and I have access to the web1 account with ssh

Its a debian Server with 2.4 Kernel

I tried the following eploits
raptor_chown (it works but it only changes the group to my gorup for the file. it doesnt change the owner to me Sad )

-rw-r----- 1 root ftponly 1406 Jul 22 02:25 /etc/shadow
The exploit gave me group access to the shadow but only r-- so i got
root:$1$zFigglP/$5a8oBKkKAnQ037SXqNFPf.:12974:0:99999:7:::
but i don't know how to decrypt the password. I uses john but its to slow Sad


Than this:
./mremap_pte

[+] kernel 2.4.20-021stab028.12.777-enterprise vulnerable: YES exploitable YES
MMAP #27136 0x47600000 - 0x47601000
[-] Failed

It says yes exploitable but then failed Sad


I dont know what i can do now.
Does someone of you know a good exploit?

Thought about using a rootkit?
You can find some good ones on LINUX's site.

If John failes (e.g. due to lack of time) backup your files and ask your rootserver-provider for a reset
Or try some exploits from milw0rm:
http://www.milw0rm.com/search.php?dong=linux+kernel
there are some exploits for 2.4 and 2.6 mainlines, they should work four you too
