Packet Storm

For various versions of Bitbucket, there is an authenticated command injection vulnerability that can be exploited by injecting environment variables into a user name. This module achieves remote code execution as the atlbitbucket user by injecting the GIT_EXTERNAL_DIFF environment variable, a null character as a delimiter, and arbitrary code into a user's user name. The value (payload) of the GIT_EXTERNAL_DIFF environment variable will be run once the Bitbucket application is coerced into generating a diff. This Metasploit module requires at least admin credentials, as admins and above only have the option to change their user name.
