Executive Summary

This vulnerability is an improper authorization issue in TaleLin lin-cms-spring-boot up to version 0.2.1. It affects the searchBook function in the BookController.java file, allowing remote attackers to query all books without proper access controls. The endpoint /v1/book/search can be accessed via a GET request without any permission verification, exposing all book details.

Detection Guidance

Check if the /v1/book/search endpoint is accessible without authentication by sending a GET request to it. Use tools like curl or a browser to access the path directly. If the endpoint returns book data without requiring credentials, the system is likely vulnerable.

Impact Analysis

An attacker could exploit this to remotely access and retrieve sensitive book-related information without authorization. Since the endpoint lacks access control, all book details stored in the database could be exposed. This may lead to data breaches or unauthorized access to confidential information.

Compliance Impact

This vulnerability could lead to non-compliance with GDPR and HIPAA by exposing sensitive data without authorization. GDPR requires protecting personal data, while HIPAA mandates safeguarding health information. Unauthorized access to book details may violate these regulations, resulting in legal penalties and reputational damage.

Mitigation Strategies

Immediately update Lin-CMS Spring Boot to a version that patches this vulnerability. If an update is unavailable, restrict access to the /v1/book/search endpoint by implementing proper authentication and authorization checks in the BookController.java file.
