Uncontrolled recursion in the json2pb component in Apache bRPC (version < 1.15.0) on all platforms allows remote attackers to make the server crash via sending deep recursive json data.
Root Cause: The bRPC json2pb component uses rapidjson to parse json data from the network. The rapidjson parser uses a recursive parsing method by default. If the input json has a large depth of recursive structure, the parser function may run into stack overflow.
Affected Scenarios: Use bRPC server with protobuf message to serve http+json requests from untrusted network. Or directly use JsonToProtoMessage to convert json from untrusted input.
How to Fix: (Choose one of the following options)
- Upgrade bRPC to version 1.15.0, which fixes this issue.
- Apply this patch: https://github.com/apache/brpc/pull/3099
Note: No matter which option
you choose, you should know that the fix introduces a recursion depth limit with default value 100. It affects these functions:
