# SessionManager
|
|
# --------------
|
|
#
|
|
# The purpose of the session manager is to keep track of sessions that are
|
|
# created during the course of a framework instance's lifetime. When
|
|
# exploits succeed, the payloads they use will create a session object,
|
|
# where applicable, there will implement zero or more of the core
|
|
# supplied interfaces for interacting with that session. For instance,
|
|
# if the payload supports reading and writing from an executed process,
|
|
# the session would implement SimpleCommandShell in a method that is
|
|
# applicable to the way that the command interpreter is communicated
|
|
# with.
