Oracle’s stealth password cracking vulnerability

I just read an article about how Oracle Database suffers from “stealth password cracking vulnerability“. This means someone trying to exploit this vulnerability can brute force your passwords and you would never know about it. Oracle fixed this vulnerability in the new version of the authentication protocol but decided not to patch the previous version. Therefore, everyone running Oracle 11G will need to upgrade.  Upgrading is going to be an issue for many companies running Oracle 11G since either they cannot or will not upgrade for many reasons. Maybe it is time to rethink this policy in your organization. There is a paper published about the problems in the Oracle Authentication protocol, so your databases are possible being attacked right now. Because many companies do not upgrade, this vulnerability is going to be around for a long time.
