CVE-2021-33191: Apache NiFi - MiNiFi C++: MiNiFi CPP arbitrary script
execution is possible on the agent's host machine through the c2
protocol


Description:

>From Apache NiFi MiNiFi C++ version 0.5.0 the c2 protocol implements an
"agent-update" command which was designed to patch the application
binary.

This "patching" command defaults to calling a trusted binary, but might
be modified to an arbitrary value through a "c2-update" command. Said
command is then executed using the same privileges as the application
binary.

 This was addressed in version 0.10.0
