KRACK attack on WPA2

[Johannes_Dennin]

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

Thanx. The product house and development (...) has moved to Extreme, probably not many left...?

The Avaya 9100 series is still supported by Avaya. Unfortunately, I won't have an answer on that, but still may be able to get more information.

I've asked the WiNG and IdentiFi teams for an update. I'll share with the thread when I have more information.

I already have fixes for other vendor devices, but need them for the WiNG access points also, so same question.

There are updates from other vendors already:
