TITLE:
tinyBB SQL Injection and File Inclusion Vulnerabilities

SECUNIA ADVISORY ID:
SA20356

VERIFY ADVISORY:
http://secunia.com/advisories/20356/

CRITICAL:
Highly critical

IMPACT:
Manipulation of data, System access

WHERE:
>From remote

SOFTWARE:
tinyBB 0.x
http://secunia.com/product/10211/

DESCRIPTION:
Mustafa Can Bjorn has discovered some vulnerabilities in tinyBB,
which can be exploited by malicious people to conduct SQL injection
attacks and to compromise a vulnerable system.

1) Input passed to the "tinybb_footers" parameter in footers.php
isn't properly verified, before it is used to include files. This can
be exploited to include arbitrary files from external and local
resources.

Successful exploitation requires that "register_globals" is enabled.

2) Input passed to the "username" and "password" parameters in
login_form.php, and to the "q" parameter in forgot.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 confirmed in version 0.3. Other
versions may also be affected.

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