Descriptions
A Predictable Value Range from Previous Values issue was discovered in Rockwell Automation Allen-Bradley MicroLogix 1100 programmable-logic controllers 1763-L16AWA, Series A and B, Version 16.00 and prior versions; 1763-L16BBB, Series A and B, Version 16.00 and prior versions; 1763-L16BWA, Series A and B, Version 16.00 and prior versions; and 1763-L16DWD, Series A and B, Version 16.00 and prior versions and Allen-Bradley MicroLogix 1400 programmable logic controllers 1766-L32AWA, Series A and B, Version 16.00 and prior versions; 1766-L32BWA, Series A and B, Version 16.00 and prior versions; 1766-L32BWAA, Series A and B, Version 16.00 and prior versions; 1766-L32BXB, Series A and B, Version 16.00 and prior versions; 1766-L32BXBA, Series A and B, Version 16.00 and prior versions; and 1766-L32AWAA, Series A and B, Version 16.00 and prior versions. Insufficiently random TCP initial sequence numbers are generated, which may allow an attacker to predict the numbers from previous values. This may allow an attacker to spoof or disrupt TCP connections, resulting in a denial of service for the target device.
Se detectó un problema de Rango de Valor Predecible de Valores Anteriores en los controladores lógicos programables MicroLogix 1100 1763-L16AWA, Series A y B, versión 16.00 y anteriores; 1763-L16BBB, Serie A y B, versión 16.00 y anteriores; 1763-L16BWA, Serie A y B, versión 16.00 y anteriores; y 1763-L16DWD, Series A y B, versión 16.00 y anteriores de Allen-Bradley en Rockwell Automation y en controladores lógicos programables MicroLogix 1400 1766-L32AWA, Series A y B, versión 16.00 y anteriores; 1766-L32BWA, Serie A y B, versión 16.00 y anteriores; 1766-L32BWAA, Serie A y B, versión 16.00 y anteriores; 1766-L32BXB, Serie A y B, versión 16.00 y anteriores; 1766-L32BXBA, Serie A y B, versión 16.00 y anteriores; y 1766-L32AWAA, Series A y B, versión 16.00 y anteriores de Allen-Bradley en Rockwell Automation. Se generan números de secuencia inicial TCP de aleatoriedad insuficientemente, lo que puede permitir a un atacante predecir los números de los valores anteriores. Esto puede permitir a un atacante suplantar o interrumpir las conexiones TCP, resultando en una denegación de servicio para el dispositivo de destino.
