A path traversal vulnerability exists in Ansible when extracting tarballs. An attacker could craft a malicious tarball so that when using the galaxy importer of Ansible Automation Hub, a symlink could be dropped on the disk, resulting in files being overwritten.

Description Mauro Matteo Cascella 2023-08-24 09:23:04 UTC 
A vulnerability was found in the galaxy importer of Ansible Automation Hub. The tarball extraction code is open to abuse in several ways (relative paths in the middle of a path, as well as symlinks that target arbitrary paths). If used to extract user-provided tarballs, this flaw could lead to arbitrary file overwrite.
Comment 2 Salvatore Bonaccorso 2023-11-05 19:51:19 UTC 
Are there any details you can share about this issue? Is there an upstream report about it? Is an upstream fix known?
Comment 3 Mauro Matteo Cascella 2023-11-06 09:09:32 UTC 
Redirecting NEEDINFO to Vipul who worked on this CVE and should be able to shed some light on it. As far as I know, the affected code can be found in _extract_archive() in galaxy-importer/collection.py. I do not know if there is a patch or any upstream discussions about it, though.
Comment 4 Vipul Nair 2023-11-14 17:00:58 UTC 
The affected code can be found at https://github.com/ansible/galaxy-importer/blob/2c5c7c05fdfb0835878234b36de32902c703616d/galaxy_importer/collection.py#L160-L165

It does not protect against `..` in the middle of paths, nor does it protect against directory traversals in `linkname` only `name`.
