Who is Vulnerable?
Oracle TimesTen In-Memory Database 7.0.5
Vulnerability Description
A denial of service vulnerability was reported in Oracle TimesTen In-Memory Database service, a product designed for real-time data management. The vulnerability is due to an input validation error while parsing HTTP GET requests. Remote unauthenticated attackers can exploit this vulnerability by sending a specially crafted HTTP request to the target system, potentially resulting in a Denial of Service condition.
Vulnerability Details
The vulnerability is caused due to an error in the "timestend" daemon when processing HTTP requests. This can be exploited to crash the process via an overly large HTTP request sent to TCP port 17000.

Protection Overview
This protection will detect and block HTTP request to the Oracle TimesTen server where any CGI argument has a length that exceeds a given threshold.

In order for the protection to be activated, update your Security Gateway product to the latest IPS update. For information on how to update IPS, go to SBP-2006-05, Protection tab and select the version of your choice.
