Metasploit offers two great commands--namely pushm and popm. The pushm command pushes the current module onto the module stack, while popm pops the pushed module from the top of the module stack. However, this is not the standard stack available to processes. Rather, it is the utilization of the same concept by Metasploit; it is otherwise unrelated. Using these commands gives us speedy operations, which saves a lot of time and effort.
Consider a scenario where we are testing an internal server with multiple vulnerabilities. We have two exploitable services running on every system on the internal network. To exploit both the services on every machine, we require a fast switching mechanism between modules for both the vulnerabilities. In such cases, we can use pushm and popm commands. We can test a server for a single vulnerability using a module and...
