DESCRIPTION:
Aliaksandr Hartsuyeu has reported two vulnerabilities in
GuestBookHost, which can be exploited by malicious people to conduct
SQL injection attacks.

Input passed to the "email" and "password" fields in "config.php"
isn't properly sanitised before being used in a SQL query. This can
be exploited to manipulate SQL queries by injecting arbitrary SQL
code.

Successful exploitation requires that "magic_quotes_gpc" is
disabled.

The vulnerabilities have been reported in version 2005.04.25. Other
versions may also be affected.

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

PROVIDED AND/OR DISCOVERED BY:
