Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
CVE-2024-49766
Summary
Werkzeug is a Web Server Gateway Interface web application library. On Python < 3.11 on Windows, "os.path.isabs()" does not catch UNC paths like "//server/share". Werkzeug's "safe_join()" relies on this check, and so can produce a path that is not safe, potentially allowing unintended access to data. Applications using Python >= 3.11, or not using Windows, are not vulnerable. This issue affects versions 0.7 through 3.0.5

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.
