Telerik.Web.UI in Progress Telerik UI for ASP.NET AJAX before R1 2017 and R2 before R2 2017 SP2 uses weak RadAsyncUpload encryption, which allows remote attackers to perform arbitrary file uploads or execute arbitrary code.

According to its self-reported version number, the version of Telerik UI for ASP.NET AJAX is affected by multiple vulnerabilities in Telerik.Web.UI.dll :

 - An insecure direct object reference vulnerability due to user input used directly by RadAsyncUpload without modification or validation. (CVE-2017-11357)

 - An unrestricted file upload due to weak encryption used in old versions of Telerik.Web.UI to encrypt data used by RadAsyncUpload. (CVE-2017-11317) An unauthenticated, remote attacker can exploit this, via specially crafted data, to execute arbitrary code.

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of Sitefinity installed on the remote host is prior to 10.0.6412.0. It is, therefore, affected by multiple vulnerabilities in Telerik DialogHandler and RadAsyncUpload :

 - A cryptographic weakness exists in Telerik.Web.UI that can be exploited to disclose encryption keys

 - An unrestricted file upload vulnerability exists in Telerik.Web.UI due to weak encryption

 - An insecure direct object reference vulnerability exists in Telerik.Web.UI due to user input used directly by RadAsyncUpload without validation

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of Telerik UI for ASP.NET AJAX installed on the remote Windows host is affected by multiple vulnerabilities in Telerik.Web.UI.dll. An unauthenticated, remote attacker can exploit this, via specially crafted data, to execute arbitrary code.
