ASM url query parameter learning issue

Hi All,

 

I have installed ASM policy in transparent mode.

 

Under learning suggestions i see a parameter(url query) whose value is not learned properly.

 

Example request is https://example.com/test.asp?param1=;param2=value2;param2=value3;

 

In above request we have 3 query parameter param1 with null value, param2 with value2 as value, and param3 with value3 as value. But in learning suggestion I’m getting illegal meta character for parameter as param1 with ;param2=value2;param3=value3; as param1’s value. Learning suggestion is ignoring param2 and param3 as seperate parameter instead it consider them as part of param1 value.

 

Is there a way to resolve this query parameter learning issue wherein asm is able to properly identify all 3 parameter.

 

Thanks,

 

Sachin
