简介
在安全漏洞中,有不安全的HTTP请求方式;
原因:
1、Tomcat PUT 的上传漏洞,受影响的版本:Apache Tomcat 7.0.0 to 7.0.79
2、 Nginx 在开启 WebDAV 模式下,如果未配置认证模式,攻击者可以通过自由上传文件方法上传木马攻击服务器。
整改建议:
禁止使用GET、POST以外的HTTP方法,如PUT、DELETE、TRACE等
vue和springboot的解决方式
处理方式:
1、前端在遇到put/delete方法的时候,将该方法改为post方法,然后添加请求头
X-HTTP-Method-Override
,将真实的请求方式放入;
2、后端:编写过滤器,如果方法是post方法,且有
X-HTTP-Method-Override
参数的,然后重新转到对应的方法
vue
if(config.method.toLowerCase()==='put'){
config.method ='post'
config.headers['X-HTTP-Method-Override'] = 'put'
}elseif(config.method.toLowerCase()==='delete'){
config.method ='post'
config.headers['X-HTTP-Method-Override'] = 'delete'
}
后端
