This seems to hang indefinitely for me; logs: Eventually the Meterpreter call gets marked as timed out on msfconsole, but then the process seems to spin endlessly behind the scenes still |

After retesting, it looks like the previous bug is fixed in 2.0.164 now 👍 I ran into another issue were I psexec'd a 32 bit meterpreter, and tried to dump ssh.exe - but I wasn't able to. I think this is might just be normal windows behavior, and we might not be able to tell the user that this has happened - but it'd be good if we could do something better there. We were thinking that this functionality is pretty dope, and isn't limited to just
Maybe to remove the boilerplate: class MemorySearchModule
# or maybe platforms could be passed in instead of the `update_info` pattern :shrug:
def initialize_memory_search_module(info = {}) # /*, platforms: [] */)
# ....
register_options([
])
info
end
end
class MetasploitModule
include MemorySearchModule
def initialize(options)
super(
update_info(
initialize_memory_search_module(options) # /*, platforms: [...] */),
# ...
'Platform' => ['...'],
)
)
end

This PR adds a module that can be used to extract passwords from active OpenSSH connections on Windows where a password has been used. Private keys do not seem to be getting leaked in the same way, if at all. The affected version was
OpenSSH_9.4p1, OpenSSL 3.1.2 1 Aug 2023, with 9.5 not being affected.This PR depends on changes made here: rapid7/metasploit-payloads#686
Similar to Mettle's memory search implementation, you can modify the needle and PID to search other programs for potentially sensitive information being stored near needles.

In this scenario, the Windows target is connected to a different host using

You can also see what the username and potentially the private key used to connect is. In the below examples, I've used a user called
