Fixed Issues

Issue Resolution ID

Web Service Consumer connector has a new system property mule.soap.maxAttributeSize.

The XML parser library has a limit that specifies maximum allowed length (in characters) of attribute values. This limit protects against possible Denial-of-Service (DoS) attacks.

The default limit value is 524288 characters and it is a reasonable default value for normal usage. You can change it to a higher value if input documents can legitimately exceed the default limit, or to a lower value if specific attacks are observed or the system has a lower resource allocation. The maximum value allowed is 2147483647 (Integer.MAX_VALUE in Java). If you set 0 or if you don’t set the property, the connector takes the default value.
