Yes, if you know what you are doing.
Log onto the database server are the OS user which own the Oracle s/w; then:

sqlplus
/ as sysdba
alter user scott identified by tigger;
exit

Hi,
Which user ???
1. sys default password is "change_on_install"
2. system default password is "manager"
3. scott default password is "tiger"
4. for host_string check your tnsnames.ora file.
located: $ORACLE_HOME/network/admin

Regards
Taj

If you have OS permissions to "create password file",
then you are logged onto the OS as the owner of Oracle s/w & can logon by:
sqlplus
/ as sysdba
-- then do anything you desired to/with the database
