A vulnerability, which was classified as critical, has been found in Beckwith Electric M-6200 Digital Voltage Regulator Control (unknown version). Affected by this issue is an unknown code block of the component TCP Initial Sequence Number Handler. The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is confidentiality, and integrity. CVE summarizes:

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.

The weakness was published 06/05/2015 (Website). The advisory is available at ics-cert.us-cert.gov. This vulnerability is handled as CVE-2014-9201 since 12/02/2014. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. The technical details are unknown and an exploit is not available.

Upgrading eliminates this vulnerability.
