The login page shows a blocking page instead of CAPTCHA or shows the blocking page after resolving a CAPTCHA. Make five (configured in brute force configuration) failed login attempts and you will receive a blocking page. Blocking Reason: Resource not qualified for injection. In one instance, bd crashed.
Users are blocked after failed login attempts. bd crash that cause BIG-IP failover in HA setup or temporarily offline in standalone setup.
HTML response message has an html page with a length greater than 32000 bytes. For crashes: the problem arises when the system incorrectly handles the character encoding of HTML documents, leading to a failure during encoding transitions.
Run tmsh modify sys db asm.cs_qualified_urls value <url value>. For 'bd' crashes: No direct application-level changes are required. A fix needs to be implemented to address the system’s encoding handling.
