Yes. Log in as single-user (root). Check the permissions on /etc/passwd and /etc/shadow. From what I remember, shadow should be owned by root:root, permissions 600. passwd root:root, 644. Reboot and see if it works.
Also, you have some MAJOR security issues on your system, if you weren't the one who did this....
