![]() You might need more than just a complex code that extensively uses reflection. For most cases, automatic migration tools will help, like the one built into IntelliJ IDEA. And this is a breaking change and a big headache for migration. Starting from Hibernate 6, we need to use jakarta.persistence.* packages instead of good old javax.persistence.*. We’ll note the most significant changes in the Hibernate 6. There are release notes and migration guide for every release, and we’re not going to repeat them in this chapter. We will start with a quick review of the API changes. Now, Hibernate 6.2 is about to be released, so let’s look at the Hibernate 6.x line a bit closer. Stay within the framework for a long time and provide a base for following new features.Affect the top two points in our list: SQL generation and performance. ![]() But internal changes may be even more critical because they: Most developers focus on API changes because tools and applications typically deal with them. This article will look at Hibernate 6 both from the outside (new APIs) and the inside (new architecture). In JPA Buddy team, we recently introduced Hibernate 6 support and are now ready to share our thoughts about the new version. Hibernate 6 release was about a year ago, but proper adoption always needs to catch up. In most cases, it consists of the following (in order of importance): IntroductionĮvery Hibernate user has a list of their requirements for the next version. Every major update of this framework is a significant event that affects developers who build their applications using Hibernate and businesses which will use applications and spend money on maintenance and migrations. At first glance, it may look like it was correctly sanitized:Ĭom/logicaldoc/core/security/dao/HibernateTenantDAO.Hibernate is the most popular ORM framework in Java. This vulnerability is a very intrinsic Hibernate Injection we have found in LogicalDoc. ![]() In the following section, we will inspect real world HQL Injection vulnerabilities which were detected with static code analysis. We have tested most of these escapes and have confirmed for the latest Hibernate ORM 5 version that these exploits still work today and we have created a quick cheat sheet table at the bottom for quick reference. Since _m0bius’ talk HQL: Hyperinsane Query Language at SSTIC 2015 it is known, that an attacker can break out of the HQL syntax exploiting specific DBMS functions and the translation of HQL into SQL which is a default task performed for each query. INTO OUTFILE allowing (when granted MySQL’s FILE permissions) to spawn a backdoor prone to an unauthenticated Remote Code Execution vulnerability. Hibernates syntax will prevent the usage of DBMS specific syntax which may be critical for an adversary like MySQL’s SELECT. ![]() Of course, usually, the data that is created and manipulated by the application is accessible through an HQL Injection within that application, including usernames and password hashes of the web application administrator. Therefore, if sensitive data is stored in a SQL table that is never mapped to an entity class representing the data it cannot be accessed within HQL. Data sets stored in SQL tables must be mapped to a Java class in order to be selected through HQL.
