CVE-2017-14462

Estado: ModificadaCrítica (9.8)—

An exploitable access control vulnerability exists in the data, program, and function file permissions functionality of Allen Bradley Micrologix 1400 Series B FRN 21.2 and before. A specially crafted packet can cause a read or write operation resulting in disclosure of sensitive information, modification of settings, or modification of ladder logic. An attacker can send unauthenticated packets to trigger this vulnerability. Required Keyswitch State: REMOTE or PROG (also RUN for some) Description: Allows an attacker to enable SNMP, Modbus, DNP, and any other features in the channel configuration. Also allows attackers to change network parameters, such as IP address, name server, and domain name.
