DESCRIPTION:
Preben Nylokken has discovered a vulnerability in ASPKnowledgebase,
which can be exploited by malicious people to conduct SQL injection
attacks.

Input passed to the username and password when logging in isn't
properly sanitised before being used in a SQL query. This can be
exploited to manipulate SQL queries by injecting arbitrary SQL code.

This can further be exploited to bypass the authentication process
and access the administration section where arbitrary HTML and script
code can be inserted into the front page.

The vulnerability has been confirmed in the latest available version.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.

PROVIDED AND/OR DISCOVERED BY:
