# Wizfi modules and Ripple20 vulnerability

## Question

Asked by Blue112358 on 2020-07-09 in Wireless.

Hello everyone,
I am currently using the WizFi210 in a product. Does anybody know if any of the WizFi chips are affected by the Ripple20 vulnerability that is related to the use of the Treck TCP/IP stack. Thank you.

Have not received an answer so perhaps I’ll rephrase my question. All I need to know is whether Wiznet Wifi modules use the Treck TCP/IP stack or not.
FYI its in relation to this set of vulnerabilities [Ripple20 - Wikipedia](https://en.wikipedia.org/wiki/Ripple20)
Thanks again.

Have you been able to confirm if the units are affected by Ripple20?
