How the CVE Works
CVE-2025-3600 is an unsafe reflection vulnerability in Progress® Telerik® UI for AJAX (versions 2011.2.712 to 2025.1.218). Attackers can exploit improper input validation in deserialization processes, leading to unhandled exceptions. This crashes the hosting process, causing denial of service (DoS). The flaw occurs when maliciously crafted data triggers unintended type loading via .NET reflection, bypassing security checks.
