Fixed In:

Opened: Feb 23, 2023

Severity: 4-Minor


In BIG-IP version all 15.1 builds, when protected object filter is selected in Security > DoS overview page, it displays following error: Error : DoS Overview (non-HTTP) - A null pointer was passed into a function Schema changes updated in BIG-IP version 15.1.8 which added context_name and context_type to the mcp_network_attack_data_stat_t structure used to report DoS attack stats. The MCP code that fills in these fields in the structure when responding to the stats request was not inculded, thus an attempt to get the stats, result in detection of a NULL pointer.


This issue avoids usage of GUI partially.


Configure a protection profile. Create a protected object by attaching the protection profile. Select protected object filter in DoS Overview (non-HTTP) page.



Fix Information

Updates are implemented to compile the required fields so that NULL pointer is not returned and selected protected object is returned.
