Vulnerabilities

Autolab is a course management service that enables auto-graded programming assignments. A user can modify their first and or last name to include a valid excel / spreadsheet formula. When an instructor downloads their course's roster and opens, this name will then be evaluated as a formula. This could lead to leakage of information of students in the course roster by sending the data to a remote endpoint. This issue has been patched in the source code repository and the fix is expected to be released in the next version. Users are advised to manually patch their systems or to wait for the next release. There are no known workarounds for this vulnerability.

Autolab is a course management service that enables auto-graded programming assignments. From Autolab versions v.3.0.0 onward students can download all assignments from another student, as long as they are logged in, using the download_all_submissions feature. This can allow for leakage of submissions to unauthorized users, such as downloading submissions from other students in the class, or even instructor test submissions, given they know their user IDs. This issue has been patched in commit `1aa4c769` which is not yet in a release version, but is expected to be included in version 3.0.3. Users are advised to either manually patch or to wait for version 3.0.3. As a workaround administrators can disable the feature.

Autolab is a course management service that enables auto-graded programming assignments. There is a vulnerability in version 3.0.1 where CAs can view or edit the grade for any submission ID, even if they are not a CA for the class that has the submission. The endpoints only check that the CAs have the authorization level of a CA in the class in the endpoint, which is not necessarily the class the submission is attached to. Version 3.0.2 contains a patch. No known workarounds are available.

Autolab, a course management service that enables auto-graded programming assignments, has misconfigured reset password permissions in version 3.0.0. For email-based accounts, users with insufficient privileges could reset and theoretically access privileged users' accounts by resetting their passwords. This issue is fixed in version 3.0.1. No known workarounds exist.

Autolab is a course management service that enables instructors to offer autograded programming assignments to their students over the Web. Path traversal vulnerabilities were discovered in Autolab's assessment functionality in versions of Autolab prior to 2.12.0, whereby instructors can perform arbitrary file reads. Version 2.12.0 contains a patch. There are no feasible workarounds for this issue.

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.

Autolab is a course management service, initially developed by a team of students at Carnegie Mellon University, that enables instructors to offer autograded programming assignments to their students over the Web. A remote code execution vulnerability was discovered in Autolab's MOSS functionality, whereby an instructor with access to the feature might be able to execute code on the server hosting Autolab. This vulnerability has been patched in version 2.10.0. As a workaround, disable the MOSS feature if it is unneeded by replacing the body of `run_moss` in `app/controllers/courses_controller.rb` with `render(plain: "Feature disabled", status: :bad_request) && return`.
