2016-04-13漏洞描述
The Apache Struts frameworks when forced, performs double evaluation of attributes' values assigned to certain tags so it is possible to pass in a value that will be evaluated again when a tag's attributes will be rendered.解决建议
Adding a proper validation of each value that's coming in and it's used in tag's attributes.Don't use forced evaluation of an attribute other than value using %{...} syntax unless really needed for a valid use-case.
By upgrading to Struts 2.3.20.3, 2.3.24.3 and 2.3.28, possible malicious effects of forced double evaluation are limited.
