Oracle Advisory: Various Cross-Site-Scripting Vulnerabilities in Oracle Reports

["Kornbrust, Alexander" <ak () red-database-security com>]

Hello

3 months ago (15-april-2005) I informed the Oracle Security Team
(secalert_us () oracle com) that I will publish bug details if the bugs are
not fixed with the next critical patch update (CPU July 2005). I know
that Oracle products are complex and a good patch quality need some
time. That's why I offered Oracle additional time if 3 months are not
sufficient for fixing the bugs. Oracle never asked for more time.

Oracle's behaviour not fixing critical security bugs for a long time
(over 650 days) is not acceptable for their customers. Oracle put their
customers in danger. At least one critical vulnerability can be abused
from any attacker via internet.

I decided to publish these vulnerabilities because it is possible to
mitigate the risk of these vulnerabilities by using the workarounds
provided in the advisories.


Kind Regards
