Background

org.jboss.resteasy:resteasy-client is a Maven package that provides a client framework for RESTful web services. It is commonly used in Java applications to interact with REST APIs. The package includes the JacksonJsonpInterceptor class, which is responsible for handling JSONP requests. JSONP (JSON with Padding) is a technique used to overcome the same-origin policy in web browsers. However, the implementation of JacksonJsonpInterceptor in RESTEasy is vulnerable to a cross-site script inclusion (XSSI) attack.

Vulnerability Detail

The vulnerability in JacksonJsonpInterceptor allows remote attackers to conduct a cross-site script inclusion (XSSI) attack. This type of attack occurs when an attacker is able to include an external script from a different domain into a target web page. By exploiting this vulnerability, an attacker can execute malicious scripts in the context of the vulnerable application, potentially leading to unauthorized access, data theft, or other security breaches.

How To Fix

Minimum fixed version

3.0.20.Final

Conclusion

In conclusion, the org.jboss.resteasy:resteasy-client package is vulnerable to a cross-site script inclusion (XSSI) attack due to a flaw in the JacksonJsonpInterceptor class. To mitigate this vulnerability, it is crucial to upgrade to version 3.0.20.Final or later. Regularly updating dependencies is also recommended to ensure the application is protected against the latest security threats.
