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.
