Description

Various versions of Bitbucket Server and Data Center are vulnerable to
an unauthenticated command injection vulnerability in multiple API endpoints.

The `/rest/api/latest/projects/{projectKey}/repos/{repositorySlug}/archive` endpoint
creates an archive of the repository, leveraging the `git-archive` command to do so.
Supplying NULL bytes to the request enables the passing of additional arguments to the
command, ultimately enabling execution of arbitrary commands.
