CVE-2021-33191

Published: Aug 24, 2021

PUBLISHED

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

Vendor	Product	Versions
Apache Software Foundation	Apache NiFi - MiNiFi C++	affected `0.5.0 - < Apache NiFi - MiNiFi C++*`
