Dear Bugtraq Reader 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.

It enables businesses to give immediate access to information to all levels within and outside of the organization in an unrivaled scalable and secure environment. Oracle Reports, a component of the Oracle Application Server, is used by Oracle itself for the E-Business Suite. Many large customers are using Oracle Reports as reporting tool for their enterprise applications. By specifing a special value for the parameter desname Oracle Reports can overwrite any file on the application server. On Windows systems an attacker can overwrite any files (e.g. boot.ini) on the application server. On UNIX system an attacker can overwrite all files (e.g. opmn.xml) which belongs to the Oracle Application Server user. This attack can be done with a simple URL. TestURL ####### Will be provided if a patch is available. Workaround ########## Available at http://www.red-database-security.com/advisory/oracle_reports_overwrite_any_file.html Affected systems ################ All versions of Oracle Reports are affected.
