Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
The packages code.cloudfoundry.org/archiver and github.com/cloudfoundry/archiver versions prior to 0.0.0-20180523222229-09b5706aa936 are vulnerable to path traversal. Due to improper path sanitization, archives containing relative file paths can cause files to be written (or overwritten) outside of the target directory.
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.
