CVE-2025-49002Public exploitNetwork attack vector

Unauthenticated code execution via case-sensitive JDBC filtering

Published Jun 3, 2025 · Updated Jun 4, 2025

H2 datasource validation in FIT2CLOUD DataEase before 2.10.10 allows remote attackers to execute code through a crafted JDBC URL. CalciteProvider.getConnection passes the supplied URL to the H2 driver after a case-sensitive blocklist rejects only uppercase INIT and RUNSCRIPT, so mixed-case directives load and run remote SQL. No valid secret is required: token forgery reaches validation, and the server opens the connection after secret verification fails, yielding command execution with service privileges.
