Remote command injection vulnerability in heap profiler builtin service in Apache bRPC ((all versions < 1.15.0)) on all platforms allows attacker to inject remote command.
Root Cause: The bRPC heap profiler built-in service (/pprof/heap) does not validate the user-provided extra_options parameter and executes it as a command-line argument. Attackers can execute remote commands using the extra_options parameter..
Affected scenarios: Use the built-in bRPC heap profiler service to perform jemalloc memory profiling.
How to Fix: we provide two methods, you can choose one of them:
1. Upgrade bRPC to version 1.15.0.
2. Apply this patch ( https://github.com/apache/brpc/pull/3101 ) manually.

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)
1. Upgrade bRPC to version 1.15.0, which fixes this issue.
2. 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:
ProtoMessageToJson, ProtoMessageToProtoJson, JsonToProtoMessage, and ProtoJsonToProtoMessage.
If your requests contain json or protobuf messages that have a depth exceeding the limit, the request will be failed after applying the fix. You can modify the gflag json2pb_max_recursion_depth to change the limit.
