Hi, I am trying to integrate F5 ASM WAF with OPSWAT metadefender but when I try and upload and EICAR file browser just shows a blank white page. I am using a default security policy in blocking mod...

Hi Ivan,

After making the changes you suggested we have tested again, unfortunately without any change in behavour.

To clarify some more: we don't want a popup to appear, we want that the Blocking Page Default with our custom response body (in json format) is returned in stead of the html/script code that is presented, so that the web page can act on that json code.

Do you still see "TSbd/xxxx?type=5" in your blocking page?

In general, in v 15.1.1, it means, that "client side challenge" functionality is enabled in one of the features in your policy and appropraite client side challenge can not be resolved by client, that is why you see whitepage.

 

Do you see name of detected virus in violation details of "Virus detected" violation?

 

Thaks, Ivan
