Telerik UI for ASP.NET AJAX 2009.1.311 < 2026.2.708 RadChart ChartImage.axd File Read

medium Nessus Plugin ID 351481

Language:

Synopsis

The remote host has a web application development framework that is affected by an information disclosure vulnerability.

Description

The version of Progress Telerik UI for ASP.NET AJAX installed on the remote Windows host is 2009.1.311 or later and prior to 2026.2.708. It is, therefore, affected by an information disclosure vulnerability. The obsolete RadChart component's ChartImage.axd handler is vulnerable to unauthenticated file read and deletion of image-extension files within the application directory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Progress Telerik UI for ASP.NET AJAX version 2026.2.708 (2026 Q2 SP1) or later.
