TITLE:
Tutti Nova "TNLIB_DIR" File Inclusion Vulnerabilities

SECUNIA ADVISORY ID:
SA21572

VERIFY ADVISORY:
http://secunia.com/advisories/21572/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Tutti Nova 1.x
http://secunia.com/product/11610/

DESCRIPTION:
SHiKaA has discovered some vulnerabilities in Tutti Nova, which can
be exploited by malicious people to compromise a vulnerable system.

Input passed to the "TNLIB_DIR" parameter in multiple files is not
properly verified before being used to include files. This can be
exploited to execute arbitrary PHP code by including files from local
or external resources.

Examples:
http://[host]/include/novalib/class.novaEdit.mysql.php?TNLIB_DIR=[file]
http://[host]/include/novalib/class.novaAdmin.mysql.php?TNLIB_DIR=[file]
http://[host]/include/novalib/class.novaRead.mysql.php?TNLIB_DIR=[file]

Successful exploitation requires that "register_globals" is enabled.

The vulnerabilities have been confirmed in version 1.6. Other
versions may also be affected.

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

Restrict access to the "include" directory e.g. via a .htaccess file.

PROVIDED AND/OR DISCOVERED BY:
