HTTP 客户端编程中最常碰见的问题,很多网站的内容都只是对注册用户可见的,这种情况下就必须要求使用正确的用户名和口令登录成功后,方可浏览到想要的页面.因 为HTTP协议是无状态的,也就是连接的有效期只限于当前请求,请求内容结束后连接就关闭了.在这种情况下为了保存用户的登录信息必须使用到Cookie 机制.以JSP/Servlet为例,当浏览器请求一个JSP或者是Servlet的页面时,应用服务器会返回一个参数,名为jsessionid(因不 同应用服务器而异),值是一个较长的唯一字符串的Coo
很多WEB开发语言为了防止浏览器禁止了cookie而无法识别用户,允许在URL中携带sessionid,这样虽然方便,但却有可能引起钓鱼的安全漏洞. 图示: 下图是从测试组发来的安全报告中剪出来的,图有些小问题,本来想重画1个,在visio中没找到合适的图.所以只能用别人的图了. 说明: 让我们对上图的步骤进行详细说明: 1. 黑客用自己的帐号登录,假设登录页面是:http://www.abc.com/login.jsp 2. 服务器返回登录成功. 3. 黑客从cookie中查看自己的sessi
