Description
This module exploits an authentication bypass vulnerability in JetBrains TeamCity. An unauthenticated
attacker can leverage this to access the REST API and create a new administrator access token. This token
can be used to upload a plugin which contains a Metasploit payload, allowing the attacker to achieve
unauthenticated RCE on the target TeamCity server. On older versions of TeamCity, access tokens do not exist
so the exploit will instead create a new administrator account before uploading a plugin. Older version of
TeamCity have a debug endpoint (/app/rest/debug/process) that allows for arbitrary commands to be executed,
however recent version of TeamCity no longer ship this endpoint, hence why a plugin is leveraged for code
execution instead, as this is supported on all versions tested.
