Foundstone Research Labs Advisory - 091802-ISSC
Advisory Name: Remotely Exploitable Buffer Overflow in ISS Scanner
Release Date: September 18, 2002
Application: ISS Scanner 6.2.1
Platforms: Windows NT/2000/XP
Severity: Remote code execution
Vendors: Internet Security Systems (http://www.iss.net)
Authors: Tony Bettini (email@example.com)
CVE Candidate: CAN-2002-1122
The license banner HTTP check performed by ISS Scanner does not check
length of the data returned by the web server being tested. As a result,
a malicious host could be configured to return a long HTTP response that
causes code execution on the ISS Scanner host.
A malicious web server could be setup to return a long HTTP result code,
such that when the ISS Scanner attempts to perform a license
advertisement via an HTTP banner check, a reply is returned that
executes arbitrary code on the ISS Scanner host.
ISS has issued a fix for this vulnerability. It is included within
X-Press Update 6.17.
We recommend applying the vendor patch.
