Unparsable request content - which security tradeoff ?

Hi JG, Absolutely. I talked to the app team before, and this behaviour would be consequence of mini applications inside the application page. I will make them aware of the security issue that this implies.

Hi Aurel,JG

This is Santosh.

I am new to F5, I am also facing the same issue. I can ask the application team to make it as a post method. But my question is in details of this violation it is showing "URL length: 3610 exceeded maximum limit of: 3096". I am bit curious how this 3610 is been calculated. I tried to match this 3610 with the request URI but is no where matching. actually there is very big query string content which is more number of bytes than 3096. Can you help me to understand how it will be calculated.

 

Thanks in advance,
Santosh. M
