Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Multiple directory traversal vulnerabilities in AIST NetCat 3.12 and earlier, when magic_quotes_gpc is disabled and register_globals is enabled, allow remote attackers to include and execute arbitrary local files via a .. (dot dot) in (1) the system parameter in modules/netshop/post.php; and the INCLUDE_FOLDER parameter in (2) auth.inc.php, (3) banner.inc.php, (4) blog.inc.php, and (5) forum.inc.php in modules/.
CWE-22 - Path Traversal
Path traversal (or directory traversal), is a vulnerability that allows malicious users to traverse the server's root directory, gaining access to arbitrary files and folders such as application code & data, back-end credentials, and sensitive operating system files. In the worst-case scenario, an attacker could potentially execute arbitrary files on the server, resulting in a denial of service attack. Such an exploit may severely impact the integrity, confidentiality, and availability of an application.
