In version 6.5 of Microchip MiWi software and all previous versions including legacy products, there is a possibility of frame counters being validated/updated prior to the message authentication. With this vulnerability in place, an attacker may increment the incoming frame counter values by injecting messages with a sufficiently large frame counter value and invalid payload. This results in denial of service/valid packets in the network. There is also a possibility of a replay attack in the stack. En la versión 6.5 del software Microchip MiWi y en todas las versiones anteriores, incluidos los productos heredados, existe la posibilidad de que los contadores de tramas se validen/actualicen antes de la autenticación del mensaje. • https://ww1.microchip.com/downloads/en/DeviceDoc/asf-release-notes-3.50.0.100-readme.pdf https://www.microchip.com/en-us/development-tools-tools-and-software/libraries-code-examples-and-more/advanced-software-framework-for-sam-devices#Downloads https://www.microchip.com/en-us/products/wireless-connectivity/software-vulnerability-response/miwi-software-vulnerability https://www.microchip.com/en-us/products/wireless-connectivity/sub-ghz/miwi-protocol https://www.microchip.com/product-change-notifications/# • CWE-670: Always-Incorrect Control Flow Implementation •
