Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Multiple directory traversal vulnerabilities in CyBoards PHP Lite 1.21 allow remote attackers to include and execute arbitrary local files via directory traversal sequences in the (1) script_path parameter to (a) options.php and the (2) lang_code parameter to (b) copy_vip.php and (c) process_edit_board.php in adminopts/. NOTE: some of these vectors might not be vulnerabilities under proper installation.
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.
