CVE-2021-32098Network attack vector

Unauthenticated code execution via PHAR graph deserialization

Published May 7, 2021 · Updated Aug 3, 2024

Phar deserialization in Artica Pandora FMS 742 allows remote attackers to execute arbitrary code through unauthenticated graph requests. The fgraph.php progressbar and progressbubble graph handlers trigger PHAR metadata deserialization from attacker-controlled input. No account or special configuration is required; successful exploitation executes code on the Pandora FMS server and exposes connected monitoring systems.
