Struts2 漏洞彻底解决办法

我们目前推荐在原有过滤的基础上，增加一个patch包以对底层调用过滤,随后，公司内部已经布一个ongl_patch.jar,基本上引入后，在项目的servlet/struts/spring 任何一个框架的listener里调用里面的方法初始化一下，就可以了

其实质就是做如下初始化:

OgnlRuntime.setMethodAccessor(OgnlTest.class, new NoMethodAccessor());
OgnlRuntime.setMethodAccessor(Runtime.class, new NoMethodAccessor());
OgnlRuntime.setMethodAccessor(System.class, new NoMethodAccessor());
OgnlRuntime.setMethodAccessor(ProcessBuilder.class,
new NoMethodAccessor());
OgnlRuntime
.setMethodAccessor(OgnlRuntime.class, new NoMethodAccessor());

NoMethodAccessor实现了OGNL的 MethodAccessor，

如下：

public class NoMethodAccessor implements MethodAccessor {

public NoMethodAccessor() {
int i = 1;
}

@Override
public Object callStaticMethod(Map context, Class targetClass,
String methodName, Object[] args) throws MethodFailedException {
throw new MethodFailedException("do not run", "123");
}

@Override
public Object callMethod(Map context, Object target, String methodName,
Object[] args) throws MethodFailedException {
// TODO Auto-generated method stub
throw new MethodFailedException("do not run", "123");
}

}
