Description

CookieInterceptor in Apache Struts before 2.3.20, when a wildcard cookiesName value is used, does not properly restrict access to the getClass method, which allows remote attackers to "manipulate" the ClassLoader and execute arbitrary code via a crafted request. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-0094.

Affected products

Apache Struts: from 2.0.0 before 2.3.16.2 — fixed in 2.3.16.2

How to fix

Upgrade to a fixed version: Apache Struts 2.3.16.2. Check the vendor advisory for mitigations.
