Autolab tar slip in Install Assessment functionality (`GHSL-2023-081`)
Summary
Autolab tar slip in Install Assessment functionality (GHSL-2023-081)
Original description
The description as published by the source.
Autolab is a course management service that enables auto-graded programming assignments. A Tar slip vulnerability was found in the Install assessment functionality of Autolab. To exploit this vulnerability an authenticated attacker with instructor permissions needs to upload a specially crafted Tar file. Using the install assessment functionality an attacker can feed a Tar file that contain files with paths pointing outside of the target directory (e.g., ../../../../tmp/tarslipped1.sh). When the Install assessment form is submitted the files inside of the archives are expanded to the attacker-chosen locations. This issue has been addressed in version 2.11.0. Users are advised to upgrade.
