CVE-2023-41887Public exploitNetwork attack vector

Unauthenticated code execution via injected JDBC parameters

Published Sep 15, 2023 · Updated Sep 25, 2024

Remote code execution in OpenRefine 3.7.4 and earlier allows remote attackers to run arbitrary code through a crafted MySQL import. The MySQL connection manager directly concatenates the database name into a JDBC URL, allowing injected autoDeserialize and queryInterceptors parameters to activate Connector/J deserialization and a Commons BeanUtils gadget chain. The OpenRefine service must be network-reachable and connect to an attacker-controlled MySQL server; successful exploitation runs code with the server process's privileges.
