[SOLVED] Is ESP8266 AT command firmware affected by KRACK?

Postby t310h » Wed Oct 25, 2017 8:50 am

I'm aware that libwpa.a and some other libraries are already updated.
However, how about AT command firmware?

Yesterday, I ran AT+CIUPDATE. But AT+GMR reports

AT version:1.5.0.0(Sep 20 2017 19:34:38)
SDK version:2.1.0(116b762)
compile time:Sep 20 2017 20:32:34
OK

Is this version affected by KRACK (WPA2 attack)?

I have successfully updated AT firmware to the unvulnerable version(SDK2.1.0(ace2d95)).
Thank you for the revision.

Hi,

Can you tell me where you downloaded the new AT firmware from?

Hello,

First, open the resources page of ESP8266:

http://espressif.com/en/products/hardware/esp8266ex/resources

ant click the check mark (looks like a letter v) at the right of AT.
(DO NOT click 'SDK & Demos'. As of writing this, the AT firmwares there are still old ones.)
Then a table will appear.
Confirm that release date is 2017.11.06 (or later) and click the download icon.
You'll obtain a zip file containing new firmwares.

Alternatively, if your current AT firmware is capable of AT+CIUPDATE, then you might want to try it.

Hope this helps.
