Background
Hibernate Validator is a popular Java library used for bean validation. It provides a set of annotations and APIs to validate objects and their properties. This vulnerability affects Hibernate Validator versions 6.1.0.Final to 6.1.4.Final. The library is commonly used in Java applications to ensure data integrity and enforce validation rules. However, a flaw in the message interpolation processor allows invalid EL expressions to be evaluated as if they were valid. This can bypass input sanitation controls and potentially lead to security vulnerabilities when handling user-controlled data in error messages.
Vulnerability Detail
The vulnerability (CVE-2020-10693) in Hibernate Validator allows attackers to bypass input sanitation controls by exploiting a bug in the message interpolation processor. This bug enables the evaluation of invalid EL expressions as if they were valid. As a result, developers' efforts to sanitize user-controlled data in error messages can be circumvented. Attackers can potentially inject malicious code or perform other unauthorized actions by exploiting this vulnerability. The impact of this vulnerability depends on the specific implementation and usage of Hibernate Validator in the affected application.
How To Fix

Workaround
As a workaround, developers can manually sanitize user-controlled data in error messages by properly escaping or stripping any potentially dangerous characters or expressions. However, this approach is error-prone and may not provide complete protection. It is strongly recommended to apply the official fix by upgrading to the latest version of Hibernate Validator.
Conclusion
The vulnerability in Hibernate Validator allows attackers to bypass input sanitation controls and potentially exploit the application. It is crucial to upgrade to the latest version of Hibernate Validator (6.1.5.Final or later) to mitigate this vulnerability. Developers should also ensure that their project dependencies are regularly updated to include the latest security patches.
