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.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
