Arbitrary file write via unsanitized archive paths
Published Aug 30, 2023 · Updated Oct 1, 2024
Path traversal in marmelroy Zip 2.1.2 and earlier allows context-dependent attackers to write files via a crafted ZIP entry. The unzipFile function appends an archive entry's pathString to the destination directory without sanitizing parent-directory components. Exploitation requires an application to extract an attacker-controlled archive and permits writes outside the intended extraction directory, including overwriting accessible files.
