Patch Available for "Site Wizard Input Validation" Vulnerability
Originally Posted: February 18, 2000

Summary
=======
Microsoft has released a patch that eliminates a security vulnerability
in web applications associated with Microsoft® Site Server 3.0, Commerce
Edition. These applications are provided as samples and generated by
wizards, but do not follow security best practices. If deployed on a
web site, they could allow inappropriate access to a database on the
site. Frequently asked questions regarding this vulnerability and the
patch can be found at
http://www.microsoft.com/technet/security/bulletin/fq00-010.asp.

Issue
=====
Two sample web sites provided as part of Site Server 3.0, Commerce
Edition do not follow security best practices; the code generated by
one of the wizards is affected by the same problem. The code requests
an identification number as one of the inputs, but does not validate
it before using it in a database query. As a result, a malicious user
could, instead of entering an appropriate input, provide SQL commands.
If this were done, the SQL commands would be executed as part of the
query, and could be used to create, modify, delete or read data in the
database.

The vulnerability only affects sites that have either deployed the code
at issue here, or have used the code as a model for developing custom code.
Customers who have deployed the code should apply the patch to ensure that
security best practices are followed. Customers who have used the code as a
guide in developing their own should refer to the Knowledge Base article
referenced below for specific code changes.
