CVE-2017-12093
An exploitable insufficient resource pool vulnerability exists in the session communication functionality of Allen Bradley Micrologix 1400 Series B Firmware 21.2 and before.
Does this matter?
Lower severity and a low EPSS score (6.00%). Track it; it rarely justifies an emergency change on its own.
Description
An exploitable insufficient resource pool vulnerability exists in the session communication functionality of Allen Bradley Micrologix 1400 Series B Firmware 21.2 and before. A specially crafted stream of packets can cause a flood of the session resource pool resulting in legitimate connections to the PLC being disconnected. An attacker can send unauthenticated packets to trigger this vulnerability.
