Path traversal in RadChart in Telerik UI for ASP.NET AJAX allows a remote attacker to read and delete an image with extension .BMP, .EXIF, .GIF, .ICON, .JPEG, .PNG, .TIFF, or .WMF on the server through a specially crafted request. NOTE: RadChart was discontinued in 2014 in favor of RadHtmlChart. All RadChart versions were affected.

How SecUtils Interprets This CVE

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For progress's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
