aspcms任意用户密码重置

### 简要描述： aspcms会员中心的某些页面，对用户的验证存在缺陷，修改cookie后提交即可重置任意用户的帐号信息。 ### 详细说明： ``` 'member/reg.asp dim action : action=getform("action","get") if action = "reg" then addUser() elseif action = "editpass" then editUser() else echoContent() end if '第3-10行 接受一个get请求,如果action为editpass时候执行editUser过程 Sub editUser dim LoginName,userPass,reuserPass,Email,Mobile,Address,PostCode,Gender,QQ,TrueName,Phone LoginName=trim(rCookie("loginName")) userPass=getForm("userPass","post") reuserPass=getForm("reuserPass","post") Email=filterPara(getForm("Email","post")) Mobile=filterPara(getForm("Mobile","post")) Address=filterPara(getForm("Address","post")) PostCode=filterPara(getForm("PostCode","post")) Gender=filterPara(getForm("Gender","post")) QQ=filterPara(getForm("QQ","post")) TrueName=filterPara(getForm("TrueName","post")) Phone=filterPara(getForm("Phone","post")) if userPass<>reuserPass then alertMsgAndGo "两次输入密码不相同","-1" dim passStr if not isnul(userPass) then passStr="[Password]='"&md5(userPass,16)&"'," Conn.Exec"update {prefix}User set "&passStr&" Email='"&Email&"',QQ='"&QQ&"',Mobile='"&Mobile&"',Address='"&Address&"',PostCode='"&PostCode&"',Gender="&Gender&",Phone='"&Phone&"',TrueName='"&TrueName&"' where LoginName='"&LoginName&"'","exe" alertMsgAndGo "修改成功","editPass.asp" End Sub '第24-47行 是editUser过程 '从中可以看出，对用户修改密码根本没做任何验证，cookie值是我们可以修改的 '将LoginName值修改为admin提交修改即可重置管理员信息 '同样存在此问题的还有userinfo.asp 页面 ``` ### 漏洞证明： [<img src="https://images.seebug.org/upload/201206/03010854ab67fa4dad36c43b0308362e3773e45b.jpg" alt="" width="600" onerror="javascript:errimg(this);">](https://images.seebug.org/upload/201206/03010854ab67fa4dad36c43b0308362e3773e45b.jpg)
