Oracle problem:

UNIX Oracle 7.1 and 7.2 store install-time "system" account passwords
in $ORACLE_HOME/network/config/sql/add*_net.sql in plain text.
Previous versions of Oracle may also be affected.

Knowledge of the "system" password allows you to manipulate the
database at will.

This is supposedly fixed in 7.3. Oracle didn't find it
necessary to inform customers about it. There are probably
still many <7.3 versions in heavy use. They're all vulnerable
if the password hasn't been changed after installation.

Yours,
Markus.
