Summary

Zuken Elmic KASAGO uses insufficient random values for TCP Initial Sequence Numbers

Details

Zuken Elmic KASAGO, TCP/IP protocol stack for embedded systems, uses its own random number generator function when generating TCP initial sequence numbers, which leads to use insufficient random values (CWE-330). Zuken Elmic reported this vulnerability to JPCERT/CC to notify users of its solution through JVN.
