帮朋友检测网站的安全性，用的是SMSJ Version 8.0，号称仿阿里巴巴的东西，注册企业会员后，登录管理，发现上传图片会归类到一个http://www.rover.com/UserDocument/你注册的会员帐号/picture/的目录里不由让人浮想联翩，想起早期动易的那个注册漏洞
说起这个漏洞，完
代码如下：
function checkdata() {
if( isNumberString(addform.user.value,"1234567890abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ_")!=1 || addform.user.value.length<2 || addform.user.value.length>16) {
alert("\用户注册出错，下面是产生错误的可能原因：\n\n·用户名必须是2-16位的数字、英文或下划线")
return false;
ok,抓包，然后用nc提交，直接绕过
抓包内容

nc ip 80成功注册，然后把asp木马改成gif后缀，当图片上传上去

自此得到webshell，over~最近懒的说话，懒得修饰文笔，看不懂的就一直跳过跳过...
ps:漏洞很简单，好久不写字了，纯粹憋字而已，见笑了，此外，还可以本地提交注册
