Claudius Heine commented on THRIFT-3930:
----------------------------------------
I think its more an issue with the client/server application than with the
TJSONProtocol.
Since the server/client are getting the exception of the JSONProtocol but they
didn't react to it correctly.
> C++ JSON protocol gets unresponsive when feed with invalid data

> Key: THRIFT-3930
> URL: https://issues.apache.org/jira/browse/THRIFT-3930
> Project: Thrift
> Issue Type: Bug
> Components: C++ - Library
> Affects Versions: 0.9.3
> Environment: Linux armv7
> Reporter: Pascal Bach
> Labels: security
>
> When I send invalid data to service via TJSONProtocol it gets unresponsive
> until all the data is processed.
> When I send for example the following string via POST:
> {{[1,"0123456789",1,0,{"1":{"str":"0123456789"}}]0123456789"}}
> The server responds with:
> {{[1,"0123456789",3,0,{"1":{"str":"Invalid method name:
> '0123456789'"},"2":{"i32":1}}]}}
> On the server side I get messages like:
> {{Thrift: Fri Jan 1 00:10:52 2010 TConnectedClient protocol exception:
> Expected '['; got '6'.}}
> This messages keep coming long after the response was already received.
> If multiple requests like the ones above are made the server is blocked for a
> long time doing nothing but printing the above mentioned messages.
> This allows to easily do denial of service towards the server.
