Oracle Reports Server Reports Web Cartridge (RWCGI60) vulnerable to buffer overflow via database name parameter

Vulnerability Note VU#997403

Original Release Date: 2002-06-04 | Last Revised: 2002-11-15

Overview

A buffer overflow vulnerability in Oracle Reports Server 6i could allow an unauthenticated, remote attacker to execute arbitrary code with the privileges of the Reports Server process.

Description

Oracle Reports Server is a component of Oracle Application Server that handles client requests for reports from multiple data sources. Oracle Reports Server is capable of accepting requests and delivering reports over the web using a Reports Web Cartridge (RWCGI60). RWCGI60 is a CGI program that translates and delivers information between the Oracle HTTP Server and the Oracle Reports Server. According to a report by NGSSoftware, RWCGI60 is vulnerable to a buffer overflow via an HTTP request containing a specially crafted database name parameter.

According to Oracle Security Alert #35, Oracle Reports Server 6.0.8.18.0 and earlier are vulnerable, and Oracle9i Application Server 1.0.x includes a vulnerable version of Oracle Reports Server.

Impact

An unauthenticated, remote attacker could execute arbitrary code or cause a denial of service on a vulnerable system. By default, the Oracle Reports stand-alone server runs as SYSTEM on Windows NT and Windows 2000 systems.
