Executive Summary

This vulnerability affects Progress Telerik UI for AJAX versions prior to v2026.2.708. It involves the obsolete RadChart component's ChartImage.axd handler, which allows unauthenticated file read and deletion of files with image extensions within the application directory due to a hardcoded encryption key.

Detection Guidance

Check for the presence of the RadChart component in your Telerik UI for AJAX installation. Look for ChartImage.axd handler endpoints in your web application logs or network traffic. Search for file read or deletion operations targeting image-extension files in application directories.

An attacker could exploit this to read sensitive files on the server, delete critical files, or perform unauthorized actions. This could lead to data breaches, system instability, or further compromise of the application.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR's data protection principles and HIPAA's security requirements. Non-compliance may result in legal penalties, fines, or reputational damage.

Upgrade Progress Telerik UI for AJAX to version 2026.2.708 or later. Remove or disable the obsolete RadChart component and its ChartImage.axd handler if not in use. Implement network-level restrictions to block unauthorized access to the handler.
