Cacti is a round-robin database (RRD) tool that helps create graphs from
database information and is available on multiple Linux distributions.
Remote exploitation of an input validation vulnerability in various
vendors implementations of Cacti graph creation tool allows an attacker
to make arbitrary SQL queries.
Cacti contains an input validation error in the config_settings.php

to gain access to the encrypted administrative password for Cacti. An
attacker can then attempt to crack the password and gain administrative
