CVE-2019-18935 (GCVE-0-2019-18935)

Vulnerability from cvelistv5 – Published: 2019-12-11 00:00 – Updated: 2025-10-21 23:35

Summary

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.)
