Oracle EBS - XSS Vulnerability


The Oracle E-Business Suite (EBS) is a collection of business Enterprise Resource Planning, Customer Relationship Management, and Supply Chain Management applications developed by Oracle Corporation. Interaction with the client is achieved through the Apache web server, Java technology (Applets) and several other Oracle technologies. Business data is stored in the Oracle database.


Imperva’s Application Defense Center is conducting a research of various business applications in order to devise better security solutions for them. As part of the research the team has identified an XSS vulnerability in the Oracle EBS software package.


The vulnerability can be exploited for stealing sensitive data and executing Phishing attacks. More specifically, data can be stolen from the users of the business suite, whether these are employees of the organization that deploys EBS or partners that access it in a self-service mode.
