How to fix?

Upgrade org.apache.struts:struts2-core to version 2.3.20 or higher.


org.apache.struts:struts2-core is a popular open-source framework for developing web applications in the Java programming language.

Affected versions of this package are vulnerable to Classloader manipulation via CookieInterceptor. When a wildcard cookiesName value is used, CookieInterceptor does not properly restrict access to the getClass method, which allows remote attackers to "manipulate" the ClassLoader and modify session state via a crafted request. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-0113.
