Progress Telerik UI for ASP.NET AJAX through 2019.3.1023 contains a .NET deserialization vulnerability in the RadAsyncUpload function. This is exploitable when the encryption keys are known due to the presence of CVE-2017-11317 or CVE-2017-11357 or other means. Exploitation can result in remote code execution. (As of 2020.1.114 a default setting prevents the exploit. In 2019.3.1023 but not earlier versions a non-default setting can prevent exploitation.)
