Recommendation wanted, dead or alive ;-) , of good tools that security tests SOAP and web interfaces in regards to invalid arguments, buffer overrun, invalid/malformed XML?
Also tools that exposes risk not only in the own webinterface bit also 3rd party webinterfaces (for which we might not have WSDL description file for, always).
Also good if tool can execute unattended without much understanding of the functionallity in the interfaces being tested, for example by just giving the tool an WSDL file. And produces humanly understandable logs that clearly says FAIL or PASS.
Acunetix Web Vulnerability Scanner is the best tool around to any Web Application. It covers every aspect. The only catch here is that it is a paid tool.
Another great tool to use is Netsparker. In this there is a community edition as well that is quiet useful.
