CVE-2014-9201: Beckwithelectric M-2001d Digital Tapchanger Control

Medium severity, CVSS 6.4. EPSS: 1.5% chance of exploitation in the next 30 days.

Beckwith Electric M-6200 Digital Voltage Regulator Control with firmware before D-0198V04.07.00, M-6200A Digital Voltage Regulator Control with firmware before D-0228V02.01.07, M-2001D Digital Tapchanger Control with firmware before D-0214V01.10.04, M-6283A Three Phase Digital Capacitor Bank Control with firmware before D-0346V03.00.02, M-6280A Digital Capacitor Bank Control with firmware before D-0254V03.05.05, and M-6280 Digital Capacitor Bank Control do not properly generate TCP initial sequence number (ISN) values, which makes it easier for remote attackers to spoof TCP sessions by predicting an ISN value.
