How can I access Unformatted Post Data in ASM

Hi,

 

I am getting "Illegal Meta Character in Parameter Name" violations on unformatted data in POST data area of header. There are many examples, but for example it may be a URL

 

http://www.bbc.co.uk/news/english

 

There is no formatting, it is not paramater post data, or JSON, XML or GWT, it is just text.

 

How can I access this value to disallow Meta Characters. I did try unnamed parameter, I cant use header based profiles, as there is nothing unique in there headers.

 

Any suggestions would be great

 

G

    you can check your parameter wildcard configuration at * from the following path Security ›› Application Security : Parameters : Parameters List ›› Parameter Properties

     

    without more specific details it is difficult to diagnose cause

     

    if you click down into the violation you will see the exact place the violation occurs in the request. this might give a better clue as to what is happening

     

    also may consider other areas, for example, sometimes encoding differences can cause character issues
