CVE-2023-41886Public exploitNetwork attack vector

Unauthenticated file read via JDBC URL injection

Published Sep 15, 2023 · Updated Sep 25, 2024

Arbitrary file read in OpenRefine database import before 3.7.5 allows remote attackers to read server files via a crafted MySQL JDBC URL. The database extension concatenates attacker-controlled host and database-name fields into a JDBC URL, allowing parameters such as allowLoadLocalInfile to be injected and a malicious MySQL server to return local files. No authentication is required, and the impact is confidentiality only; the attack requires network access to an OpenRefine instance with database import enabled.
