CVE-2022-37298Public exploitNetwork attack vector

Unauthenticated code execution via wildcard module trust

Published Oct 20, 2022 · Updated May 8, 2025

Improper authentication in Shinken Monitoring 2.4.3 and earlier allows remote attackers to execute code via crafted node messages. SafeUnpickler.find_class trusts every shinken.* module and class, allowing a pickle to invoke bottle._load without an allowlist. Access to a daemon's internal exchange port is sufficient, with no credentials or user interaction, and code runs on the monitoring server.
