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

问题描述

我使用的是AWS elastickbeanstalk，但我的网站一直遭到黑客入侵，而在DDOS之前，我已将其修复。现在，还有其他事情在想，是否有人可以查看此日志并看到我看不到的东西。我看到称为Telerik的东西正在访问它，但不确定是什么，但是我进行了搜索，并说这是导致远程执行代码的漏洞。一切结果是，它删除了Django / Python需要与Linux / Apache2服务器上的httpd对话的wsgi文件。任何见识都会有所帮助。

解决方法

要保护您的应用免受已知漏洞的侵扰，必须将ASP.NET AJAX的Telerik UI（Telerik.Web.UI.dll）升级到R1 2020（2020.1.114）版或更高版本，并应用建议的安全设置：

<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>
