Buffer Overflow attack for Oracle iSQL

I got this off of Bugtraq yesterday. I haven't seen many Oracle vulnerabilities, mostly SQL. However, I thought that Oracle was more in use then what it seems. For those of you that use this, here you go:

NGSSoftware Insight Security Research Advisory

Name: Oracle iSQL*Plus buffer overflow
Systems: Oracle Database 9i R1,2 on all operating systems
Severity: High Risk
Vendor URL: http://www.oracle.com/
Author: David Litchfield ([email protected])
Advisory URL: http://www.ngssoftware.com/advisories/ora-isqlplus.txt
Date: 4th November 2002
Advisory number: #NISR04112002


Description
***********
Oracle iSQL*Plus is a web based application that allows users to query the database. It is installed with Oracle 9 database server and runs on top of apache. The iSQL*Plus module is vulnerable to a classic buffer overflow vulnerability.


Details
*******
The iSQL*Plus web application requires users to log in. After accessing the default url, "/isqlplus" a user is presented with a log in screen. By sending the web server an overly long user ID parameter, an internal buffer is overflow on the stack and the saved return address is overwritten. This can allow an attacker to run arbitrary code in the security context of the web server. On most systems this will be the "oracle" user and on Windows the "SYSTEM" user. Once the web server has been compromised attackers may then use it as a staging platform to launch attacks against the database server itself.

Fix Information
***************
NGSSoftware alerted Oracle to this problem on the 18th of October and Oracle, last week, issued an alert. The Oracle bug number assigned to this issue is 2581911. Patches can be downloaded from the Oracle Metalink site http://metalink.oracle.com/.
