Detailed vulnerability description
The vulnerability allows a remote user to execute arbitrary code.
The vulnerability exists due to improper access control in the /de2api/datasource/validate endpoint when handling crafted H2 JDBC connection strings. A remote user can send a specially crafted request with a forged token and malicious JDBC URL to execute arbitrary code.
The issue can be exploited by bypassing the case-sensitive prohibition of INIT and RUNSCRIPT, and code execution occurs even when secret verification fails because the application still proceeds to establish the JDBC connection.
