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
