What is CVE-2021-28141?

A vulnerability in Progress Telerik UI for ASP.NET AJAX 2021.1.224 allows unauthorized access to critical scripts via the Telerik.Web.UI.WebResource.axd file. By manipulating the TSM_HiddenField parameter, an attacker may inject a command into the URI, potentially leading to code execution on the server. Although the vendor claims that this does not constitute a true vulnerability as the output does not reveal sensitive data or indicate actual command execution, it nonetheless poses a risk for unauthorized access.
