Synopsis

The remote host has an application installed that is affected by an information disclosure vulnerability.

Description

The version of Python installed on the remote Windows host is potentially affected by an information disclosure vulnerability due to an issue in Python 3's pydoc. An authenticated local or adjacent attacker can exploit this, by convincing another local or adjacent user to start a pydoc server could access the server and use it to disclose sensitive information belonging to the other user that they would not normally be able to access.
