Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Multiple directory traversal vulnerabilities in playSMS 0.9.3 allow remote attackers to include and execute arbitrary local files via directory traversal sequences in the (1) gateway_module parameter to plugin/gateway/gnokii/init.php and the (2) themes_module parameter to plugin/themes/default/init.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.
