Vulnerability from github – Published: 2022-05-24 17:03 – Updated: 2025-10-22 00:31

Details

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. (In 2019.3.1023 but not earlier versions, a non-default setting can prevent exploitation.)

Severity

9.8 (Critical)
