Atlassian Bitbucket is a Git management tool that enables users to create repositories to store files. Bitbucket has a vulnerability in how it sanitizes HTTP requests with null bytes, which enables command injection. An unauthenticated user with read access to a public repository or an authenticated user with read access to a private repository can exploit this vulnerability to run shell commands on the Atlassian server. The attacker sends a malicious HTTP request with URL-encoded null bytes (%00) followed by an argument (--exec), command, and null bytes followed by an argument (--remote).
