Not sure what ASM version you are on however in Advanced WAF v.15 there is a checkbox for "Base64 Decoding" when defining HTTP Headers or Parameters in the application security policy. Only meant to be enabled it if the value expected is always going to be Base64 encoded, otherwise you will get a ton of violations/errors.
