Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Multiple directory traversal vulnerabilities in the web server for Motorola SURFBoard cable modem SBV6120E running firmware SBV6X2X-126.96.36.199-SCM-02-SHPC allow remote attackers to read arbitrary files via (1) "//" (multiple leading slash), (2) ../ (dot dot) sequences, and encoded dot dot sequences in a URL request.
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.
