Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
The specific function in ASUS BMC’s firmware Web management page (Get Help file function) does not filter the specific parameter. As obtaining the administrator permission, remote attackers can use the means of path traversal to access system files.
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.
