Bitbucket Git Command Injection

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.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
