The company specializes in developing and marketing computer hardware systems and enterprise software products – particularly its own brands of database management systems. Oracle is the second-largest software maker by revenue, after Microsoft. The company also builds tools for database development and systems of middle-tier software, enterprise resource planning (ERP) software, customer relationship management (CRM) software and supply chain management (SCM) software. Larry Ellison, a co-founder of Oracle, has served as Oracle`s CEO throughout its history. He also served as the Chairman of the Board until his replacement by Jeffrey O. Henley in 2004. On August 22, 2008, the Associated Press ranked Ellison as the top-paid chief executive in the world.

Vulnerability Disclosure Timeline: ================================== 2014-04-28: Researcher Notification & Coordination (Benjamin Kunz Mejri) 2014-04-30: Vendor Notification (Oracle Sec Alert Security Team) 2014-05-03: Vendor Response/Feedback (Oracle Sec Alert Security Team) 2014-09-01: Vendor Fix/Patch (Oracle Developer Team - Acknowledgments 2014 October CPU Advisory) 2014-09-17: Public Disclosure (Vulnerability Laboratory) Discovery Status: ================= Published Affected Product(s): ==================== Exploitation Technique: ======================= Remote Severity Level: =============== Medium Technical Details & Description: ================================ A filter and persistent input validation mail encoding web vulnerability has been discovered in the official Oracle Corporation `MyOracle` service web-application. The vulnerability allows to bypass the regular web/system validation to inject own script codes in outgoing emails of the account system mail server service. The vulnerability is located in the name values of the my-oracle `registration` module. Remote attackers are able to inject in the first and lastname input fields of the registration formular own script codes via POST method request. The injected script code activates the account mail service notification which returns with the persistent code in the myoracle token activation site. The issue impact a critical risk because an attacker is able to inject own tokens or can manipulate the full mail body context. Further send notification mails by the myoracle service can also be affected by the issue. The encoding of the server does not recognize outgoing service mails which results in the persistent issue in outgoing emails. The injection point is a profile values update or directly the remote registration itself. The security risk of the persistent mail encoding and filter web vulnerability is estimated as medium with a cvss (common vulnerability scoring system) count of 3.9. Exploitation of the vulnerability requires low user interaction and no privileged application user account. Successful exploitation results in persistent session hijacking attacks, unauthorized external redirects to malicious sources and persistent manipulation of affected or connected module context.

Encode stored data of user in the dbms when processing to send service notifications by the mail info@oracle email to prevent persistent injection attacks. Security Risk: ============== The security risk of the persistent mail encoding web vulnerability in the myoracle account system web-server is estimated as medium.
