Description

The Ubiquiti UniFi Network Application versions 5.13.29 through 6.5.53 are affected by the Log4Shell
vulnerability whereby a JNDI string can be sent to the server via the 'remember' field of a POST request to the
/api/login endpoint that will cause the server to connect to the attacker and deserialize a malicious Java
object. This results in OS command execution in the context of the server application.

This module will start an LDAP server that the target will need to connect to.
