Summary

tar-fs provides filesystem bindings for tar-stream. Versions prior to 3.1.1, 2.1.4, and 1.16.6 are vulnerable to symlink validation bypass if the destination directory is predictable with a specific tarball. A workaround involves using the ignore option on non files/directories.

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.
