DESCRIPTION:
Multiple vulnerabilities have been discovered in vAuthenticate, which
can be exploited by malicious users and malicious people to conduct
SQL injection attacks.

1) Input passed to the "username" and "password" POST parameters in
vAuthenticate.php is not properly sanitised before being used in the
"authenticate()" function (auth.php) in a SQL query. This can be
exploited to manipulate SQL queries by injecting arbitrary SQL code.

2) Input passed to the "USERNAME" and "PASSWORD" cookie parameters in
e.g. admin/index.php is not properly sanitised before being used in
the "page_check()" function (auth.php) in a SQL query. This can be
exploited to manipulate SQL queries by injecting arbitrary SQL code.

3) Input passed to the "USERNAME" and "PASSWORD" cookie parameters in
chgpwd.php (when "submit" is set) is not properly sanitised before
being used in a SQL query. This can be exploited by malicious users
to manipulate SQL queries by injecting arbitrary SQL code.

NOTE: This can be exploited in combination with vulnerability #2.

4) Input passed to the "newpasswd" POST parameter in chgpwd.php (when
"submit" is set) is not properly sanitised before being used in a SQL
query. This can be exploited by malicious users to manipulate SQL
queries by injecting arbitrary SQL code.

NOTE: This can be exploited in combination with vulnerability #3.

The vulnerabilities are confirmed in version 3.0.1. Other versions
may also be affected.

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