WLC firmware 6.X.X is vulnerable. 

This vulnerability affects anything with a wireless NIC.  It's not just wireless AP but also wireless clients as well.  Patching the client will fix 9 out of 10 vulnerabilities but not CVE-2017-13082.

 

Perspective About the Recent WPA Vulnerabilities (KRACK Attacks)

thank you , you mean first upgrade WLC, becouse our WLC is Cisco 4402, the high version is 7.0.252, if upgrade to 7.0.252 can fix this WPA Vulnerable? how about AP, also need upgrade to version 15.3.3-JD7?

WiSM-1 and 4400 controllers are already end-of-support. This means Cisco is not obligated to publish a firmware for these models.
This means even though 6.X is vulnerable, Cisco will not publish a fix.

Software fix for the KRACK vulnerability is now available for download. They are 8.0.152.0, 8.2.164.0, 8.3.132.0 and 8.5.105.0.
