Symptoms

After enabling CAPTCHA locally on BIG-IP with brute force, after configured login attempts, CAPTCHA appears, but after bypassing the CAPTCHA successfully the user receives a support ID with cross-origin violation.

Impact

- blocking page appears. - on the event log cross-origin violation is triggered.

Conditions

- brute force with CAPTCHA mitigation enforced on login page. - cross-origin violation is enforced on the login page. - user fails to login until CAPTCHA appears - user inserts the CAPTCHA correctly

Workaround

- disable cross-origin violation enforcement.
