An information exposure vulnerability in Datart v1.0.0-rc.3 allows authenticated attackers to access sensitive data via a custom H2 JDBC connection string.
Datart 1.0.0-rc.3 is vulnerable to Directory Traversal. The configuration file handling of the application allows attackers to upload arbitrary YAML files to the config/jdbc-driver-ext.yml path. The application parses this file using SnakeYAML's unsafe load() or loadAs() method without input sanitization. This allows deserialization of attacker-controlled YAML content, leading to arbitrary class instantiation. Under certain conditions, this can be exploited to achieve remote code execution (RCE).
Datart 1.0.0-rc.3 is vulnerable to Directory Traversal in the POST /viz/image interface, since the server directly uses MultipartFile.transferTo() to save the uploaded file to a path controllable by the user, and lacks strict verification of the file name.
