Hi,
had the new 8.3.102.0 loaded onto a 2504 controller.
Here are the bugs I discovered and made me going back to 8.2.111
- CPU load on processor 2 at 100%
show processor cpu indicates high usage of apfReceiveTask and bcastReceiveTask
- Individual client usage statistics on dashboard show 16 kbyte for every application...
- Web Login Page (Authentication) not working > Cross-Site Attack warning in log

I have a 2504 running 8.3.102.0 and not seeing those issues. As far as browsers go, each seem to have it own issues with various GUI's.

Ok, the statistics issue might be browser related...
The CPU 100% is related to direct connected APs in combination with multicast.
They plan to fix this in the next MR

You are right, there is a bug on 8.3.102.0 OS.
When using internal WebAuth either with local user credentials or with pass-through, clients obtain an IP address and get redirected to the portal. However, after entering credentials or accepting the terms they don't get anything in return and stay stuck in "WEBAUTH_REQD" state.
Workaround:
1. Disable Web CSRF Check by running this command (non-disruptive and no WLC reboot is required):
>config network secureweb csrfcheck disable
2. Rollback to previous code.
