AWS lTelerik.Web.UI.WebResource.axd?type=rau HTTP/1.1" 404 196？

Question

我正在使用 AWS elastickbeanstalk，但我的网站一直被黑客入侵，在 DDOS 之前我修复了它。现在它的其他东西想知道是否有人可以看看这个日志并看到我看不到的东西。我看到它被称为 Telerik 的东西访问，不确定这是什么，但是，我进行了搜索，它说这是一个导致远程代码执行的漏洞。结果是它删除了 Django/Python 需要与 Linux/Apache2 服务器上的 httpd 对话的我的 wsgi 文件。任何见解都会有所帮助。

Answer 1

为了保护您的应用免受已知漏洞的影响，您必须将 Telerik UI for ASP.NET AJAX (Telerik.Web.UI.dll) 升级到 R1 2020 (2020.1.114) 或更高版本并应用推荐的安全设置：

<appSettings>
        <add key="Telerik.AsyncUpload.ConfigurationEncryptionKey" value="YOUR-FIRST-UNIQUE-STRONG-RANDOM-VALUE-UNIQUE-TO-YOUR-APP&" />
        <add key="Telerik.Upload.ConfigurationHashKey" value="YOUR-SECOND-UNIQUE-STRONG-RANDOM-VALUE-UNIQUE-TO-YOUR-APP&" />
        <add key="Telerik.Upload.AllowedCustomMetaDataTypes" value="Telerik.Web.UI.AsyncUploadConfiguration" />
</appSettings>
