Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Multiple directory traversal vulnerabilities in Kubix 0.7 and earlier allow remote attackers to (1) include and execute arbitrary local files via ".." sequences in the theme cookie to index.php, which is not properly handled by includes/head.php; and (2) read arbitrary files via ".." sequences in the file parameter in an add_dl action to adm_index.php, as demonstrated by reading connect.php.
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.
