CVE-2024-10013 Overview
CVE-2024-10013 is an insecure deserialization vulnerability in Progress Telerik UI for WinForms versions prior to 2024 Q4 (2024.4.1113). The flaw allows code execution when an application processes untrusted serialized data through vulnerable Telerik components. The weakness maps to CWE-502: Deserialization of Untrusted Data and requires local access with user interaction to exploit.
Critical Impact
Successful exploitation grants attackers arbitrary code execution in the context of the user running the affected WinForms application, compromising confidentiality, integrity, and availability.
Affected Products
- Progress Telerik UI for WinForms versions prior to 2024.4.1113
- Windows Forms applications embedding vulnerable Telerik UI assemblies
- Development environments distributing Telerik UI for WinForms libraries

Technical Details for CVE-2024-10013
Vulnerability Analysis
The vulnerability resides in how Telerik UI for WinForms deserializes objects from attacker-controlled input. When the affected components process a crafted serialized payload, the deserialization routine instantiates object types without adequate type restriction. This behavior enables gadget chains that execute arbitrary .NET code during object reconstruction.
Attackers deliver malicious serialized data through files, clipboard content, or application-specific import features that a user opens. Because the vulnerable code path runs inside the WinForms process, the resulting code executes with the privileges of the invoking user.
Root Cause
The root cause is the use of unsafe deserialization primitives that permit arbitrary type resolution. Progress documents the issue and its remediation in the Telerik Knowledge Base entry for CVE-2024-10013. The fix restricts deserialization to expected types and hardens the affected components in 2024.4.1113.
Attack Vector
Exploitation requires local access and user interaction. An attacker crafts a serialized payload embedding a known .NET deserialization gadget chain, then convinces a user to load the payload through a vulnerable Telerik-based application feature. When the application deserializes the payload, the gadget chain triggers execution of attacker-supplied commands. No verified public proof-of-concept is currently available.
Detection Methods for CVE-2024-10013
Indicators of Compromise
- Unexpected child processes such as cmd.exe, powershell.exe, or rundll32.exe spawned by a WinForms application using Telerik assemblies
- Loading of Telerik.WinControls*.dll versions earlier than 2024.4.1113 in production endpoints
- Suspicious serialized files (.bin, .dat, custom project formats) opened immediately before code execution events
Detection Strategies
- Inventory .NET assemblies on endpoints and flag any Telerik UI for WinForms version below 2024.4.1113
- Monitor for anomalous process creation chains originating from applications that embed Telerik controls
- Alert on file writes to persistence locations (Startup folders, Run registry keys) initiated by Telerik-hosted processes
Monitoring Recommendations
- Collect Sysmon Event ID 1 (process creation) and Event ID 7 (image load) to correlate Telerik DLL loads with subsequent execution
- Enable .NET ETW providers to capture deserialization activity and unusual assembly loads
- Forward endpoint telemetry to a centralized analytics platform for retroactive hunting against affected Telerik versions
How to Mitigate CVE-2024-10013
Immediate Actions Required
- Upgrade Progress Telerik UI for WinForms to version 2024.4.1113 or later across all development and production environments
- Rebuild and redistribute any downstream applications that embed the vulnerable assemblies
- Restrict user privileges on workstations that run WinForms applications processing external files
Patch Information
Progress released the fix in Telerik UI for WinForms 2024 Q4 (2024.4.1113). Remediation details and guidance are available in the Progress Telerik Knowledge Base advisory. Upgrading the NuGet package or MSI installer replaces the vulnerable Telerik.WinControls* assemblies with hardened versions.
Workarounds
- Block untrusted serialized input from reaching WinForms applications that depend on Telerik controls
- Apply application allow-listing to prevent execution of secondary payloads dropped by exploited processes
- Isolate legacy systems that cannot upgrade immediately using network segmentation and reduced user rights
