1.会话标识未更新：登录页面加入以下代码
request.getSession(true).invalidate();//清空session
Cookie cookie = request.getCookies()[0];//获取cookie
cookie.setMaxAge(0);//让cookie过期
request.getSession(true).invalidate();//清空session
Cookie cookie = request.getCookies()[0];//获取cookie
cookie.setMaxAge(0);//让cookie过期
不是很明白session的机制，高手路过可以指教一下。
2.跨站点请求伪造：
在出错的url加参数sessionid。
response.getWriter().write( "<script>parent.location.href='dbase/admin/loginJsp.action?sessionId="+sessionId+"'</script>");
response.getWriter().write( "<script>parent.location.href='dbase/admin/loginJsp.action?sessionId="+sessionId+"'</script>");
如果带参数报ssl错误，使用下面的post方式传值：
response.getWriter().write( "<script language=\"javascript\"> " + "document.write(\"<form action=dbase/admin/loginJsp.action method=post name=formx1 style='display:none'>\");" + "document.write(\"<input type=hidden name=name value='"+sessionId+"'\");" + "document.write(\"</form>\");" + "document.formx1.submit();" + "</script>" ); response.getWriter().write( "<script language=\"javascript\"> " + "document.write(\"<form action=dbase/admin/loginJsp.action method=post name=formx1 style='display:none'>\");" + "document.write(\"<input type=hidden name=name value='"+sessionId+"'\");" + "document.write(\"</form>\");" + "document.formx1.submit();" + "</script>" ); |
3.启用不安全HTTP方法
修改web工程中或者服务器web.xml,增加安全配置信息，禁用不必要HTTP方法
<security-constraint> <web-resource-collection> <url-pattern>/*</url-pattern> <http-method>PUT</http-method> <http-method>DELETE</http-method> <http-method>HEAD</http-method> <http-method>OPTIONS</http-method> <http-method>TRACE</http-method> </web-resource-collection> <auth-constraint> </auth-constraint> </security-constraint> <login-config> <auth-method>BASIC</auth-method> </login-config> |
