Severity: 1

Buffer Overflow Vulnerability in Oracle E-Business Suite

Description
A potential security vulnerability has been discovered in Oracle E-Business Suite.
The FNDWRR CGI program is vulnerable to malformed requests that may permit a
knowledgeable and malicious user to cause the FNDWRR executable to crash.
However, this crash will neither result in a Denial of Service (DoS) against Oracle
E-Business Suite, nor prevent the FNDWRR executable from reliably serving correctly
formed requests, but it may grant a user unauthorized access to Oracle E-Business
Suite.

Products Affected

• Oracle E-Business Suite 11i, Release 1 through Release 8
• Oracle Applications, All Releases

Platforms Affected
All platforms.

Required conditions for exploit
User with HTTP access to a Web Server set up to spawn the FNDWRR CGI program.

Risk to exposure

Risk to exposure is high, as any user with HTTP access and specialized
knowledge can exploit this vulnerability over the Internet to gain
unauthorized access to Oracle E-Business Suite if the conditions mentioned
above are met.

How to minimize risk

security vulnerability, but a patch is available (see below). Oracle
strongly recommends that customers follow best practices for Oracle
