Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
In some non-default installations of Esri Portal for ArcGIS versions 10.9.1 and below, a directory traversal issue may allow a remote, unauthenticated attacker to traverse the file system and lead to the disclosure of sensitive data (not customer-published content).
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.
