How NewScan reports it
COMPONENT VERSION RANGE
NewScan fingerprints Telerik UI for ASP.NET AJAX from its response and reports this CVE when the detected version falls inside the affected range below.
Unauthenticated RCE where cookie-based persistence storage is in use. RadPersistenceManager / RadDockLayout, not RadAsyncUpload, so it is a separate chain from the 13181-13184 batch and has no public exploit. Version-match only: whether a given app uses cookie-based or file-based persistence storage is not observable from outside, so the row reports the vulnerable BUILD rather than asserting the configuration.
