WEB Apache Struts Wildcard Matching OGNL Code

Hi Community!

I'm getting this reports daily (30 more or less), and I've been reading about it, and I don't know what exacatly what can I do to my firewalls to get rid of this messages, or if because of this messages they are working fine. Prosecure UTM10

Any advice?
