This module will extract user credentials from Network Shutdown Module by exploiting
|
|
a vulnerability found in lib/dbtools.inc, which uses unsanitized user input inside a
|
|
eval() call. Please note that in order to extract credentials,the vulnerable service
|
|
must have at least one USV module (an entry in the "nodes" table in mgedb.db)
