Oracle Application Server Portal 10g

CRLF injection vulnerability in webapp/jsp/calendar.jsp in Oracle Portal 10g and earlier, including 9.0.2, allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via CRLF sequences in the enc parameter.

Oracle Application Server (OracleAS) Portal 10g allows remote attackers to bypass intended access restrictions and read the contents of /dav_portal/portal/ by sending a request containing a trailing "%0A" (encoded line feed), then using the session ID that is generated from that request. NOTE: as of 20080512, Oracle has not commented on the accuracy of this report.
