Description

A remote overflow exists in Oracle Database 9i. Oracle Database 9i fails to handle an overly long user ID parameter resulting in a buffer overflow. With a specially crafted request, an attacker can cause arbitrary code to run in the security context of the web server resulting in a loss of confidentiality, integrity, and/or availability.

Technical

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.

Solution

Currently, there are no known workarounds or upgrades to correct this issue. However, Oracle has released a patch to address this vulnerability.
