MISP allowed an authenticated site administrator to set the Kafka rdkafka config setting to an arbitrary filesystem path. MISP subsequently parsed the referenced INI file and passed its options to rdkafka. A crafted attacker-controlled configuration file could use rdkafka options such as plugin.library.paths to load an external library, resulting in arbitrary code execution with the privileges of the MISP process. An attacker could leverage a MISP-writable location, such as an uploaded file or administrative image, to host the malicious configuration file.

The issue is fixed by restricting the setting to absolute .ini files located only in approved configuration directories outside the webroot and MISP upload targets.
