CWE-22

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 file disclosure vulnerability was discovered in Autolab’s remote handin feature, whereby users are able to hand-in assignments using paths outside their submission directory. Users can then view the submission to view the file’s contents. The vulnerability has been patched in version 2.10.0. As a workaround, ensure that the field for the remote handin feature is empty (Edit Assessment > Advanced > Remote handin path), and that you are not running Autolab as `root` (or any user that has write access to `/`). Alternatively, disable the remote handin feature if it is unneeded by replacing the body of `local_submit` in `app/controllers/assessment/handin.rb` with `render(plain: “Feature disabled”, status: :bad_request) && return`.

Lancet is a general utility library for the go programming language. Affected versions are subject to a ZipSlip issue when using the fileutil package to unzip files. This issue has been addressed and a fix will be included in versions 2.1.10 and 1.3.4. Users are advised to upgrade. There are no known workarounds for this issue.

Unauth. Directory Traversal vulnerability in Welcart eCommerce plugin <= 2.7.7 on WordPress.

On Windows, restricted files can be accessed via os.DirFS and http.Dir. The os.DirFS function and http.Dir type provide access to a tree of files rooted at a given directory. These functions permit access to Windows device files under that root. For example, os.DirFS(“C:/tmp”).Open(“COM1”) opens the COM1 device. Both os.DirFS and http.Dir only provide read-only filesystem access. In addition, on Windows, an os.DirFS for the directory (the root of the current drive) can permit a maliciously crafted path to escape from the drive and access any path on the system. With fix applied, the behavior of os.DirFS(“”) has changed. Previously, an empty root was treated equivalently to “/”, so os.DirFS(“”).Open(“tmp”) would open the path “/tmp”. This now returns an error.
