shell over whm !!help!!

Hi. My /etc/passwd file is scrambled and i can't access ssh with my root password. But i can access WHM, i need to run one command '# chmod a+w /etc/passwd' can i run this command over whm? or is there a file manager that i can access /etc/passwd ?
Thanks

 

yeah i know this but i can't access ssh with root password my /etc/passwd file is scrambled
i can only access WHM with root password and i need to do one of these
-chmod a file
-run a command over root account
-edit a file

i can't access ssh with root password, i can only access whm with root password..

 

yes i've tried it.
the first 2 lines of file /etc/password must be:

Code:

root:x:0:0:root:/root:/bin/bash
bin:x:1:1:bin:/bin:/sbin/nologin

but it is

Code:

root:x:0:0:root:/root:/bin/bash bin:x:1:1:bin:/bin:/sbin/nologin

this is the problem. someone accessed my server with root and scrambled this file so i can't access root account on ssh, i can only access root account with WHM
