Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Multiple directory traversal vulnerabilities in Social Engine 2.0 allow remote attackers to include and execute arbitrary local files via a .. (dot dot) in the global_lang parameter to (1) header_album.php, (2) header_blog.php, or (3) header_group.php; or (4) admin_header_album.php, (5) admin_header_blog.php, or (6) admin_header_group.php in admin/.
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.
