CVE-2020-27213

An issue was discovered in Ethernut Nut/OS 5.1. The code that generates Initial Sequence Numbers ISNs for TCP connections derives the ISN from an insufficiently random source. As a result, an attacker may be able to determine the ISN of current and future TCP connections and either hijack existin...
