Affected: Apache Software Foundation Apache bRPC

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.
