Some vulnerabilities have been discovered in Newswriter, which can be exploited by malicious people to compromise a vulnerable system.
Input passed to the "NWCONF_SYSTEM[server_path]" parameter in include/editfunc.inc.php, include/main.inc.php, admin/include/menu.inc.php, and update/include/main.inc.php is not properly verified before being used to include files. This can be exploited to include arbitrary files from local or external resources.
Successful exploitation requires that "register_globals" is enabled.
The vulnerabilities have been confirmed in version 1.4.2. Other versions may also be affected.
Solution: The vendor describes how to fix two of the vulnerabilities by applying code changes. Edit the source code to ensure that none of the affected files can be accessed directly.
