KRACK attack on WPA2

KRACK attack on WPA2

Hello everyone,
I have some questions due to the expected disclosure today on the attack possible on WPA2 SSIDs.
US-CERT has become aware of several key management vulnerabilities in the 4-way handshake of the Wi-Fi Protected Access II (WPA2) security protocol. The impact of exploiting these vulnerabilities includes decryption, packet replay, TCP connection hijacking, HTTP content injection, and others. Note that as protocol-level issues, most or all correct implementations of the standard will be affected. The CERT/CC and the reporting researcher KU Leuven, will be publicly disclosing these vulnerabilities on 16 October 2017.

- Is Extreme aware of this?
- Are Fixes ready to be released?
- Is a software fix sufficient or does hardware need to be replaced?

Thanks and best regards,

Johannes

I'm curious too. Could someone from Extreme shed some light on this?

This is my concern as well. Many other major vendors had a fix that was already put into previous updates or was released yesterday. I would have expected the same from Extreme, but that doesn't seem to be the case.

Extreme was notified in August like the other vendors. https://www.kb.cert.org/vuls/id/228519/
