CVE-2026-6022: CWE-400 Uncontrolled Resource Consumption in Progress Software Telerik UI for ASP.NET AJAX
CVE-2026-6022 is a high-severity vulnerability in Progress Telerik UI for ASP. NET AJAX versions prior to 2026. 1. 421. The RadAsyncUpload component does not properly enforce the configured maximum file upload size cumulatively during chunk reassembly, allowing attackers to upload files exceeding the intended size limit. This uncontrolled resource consumption can lead to disk space exhaustion on the affected system. There is no vendor-provided patch or official remediation guidance available at this time. The vulnerability does not impact confidentiality or integrity but can cause denial of service due to resource exhaustion.
AI Analysis
Technical Summary
Progress Telerik UI for ASP.NET AJAX versions before 2026.1.421 contain an uncontrolled resource consumption vulnerability (CWE-400) in the RadAsyncUpload component. The issue arises because the component fails to enforce the maximum upload size cumulatively when reassembling file chunks, allowing attackers to bypass size restrictions and upload files larger than configured. This can exhaust disk space on the server hosting the application. The CVSS 3.1 base score is 7.5 (high), reflecting network attack vector, no privileges required, no user interaction, and impact limited to availability. No patch or official fix has been published by the vendor as of the information provided.
Potential Impact
The vulnerability allows an attacker to cause denial of service by exhausting disk space through uploading files larger than the configured maximum size. This impacts availability but does not affect confidentiality or integrity. There are no known exploits in the wild currently. The affected versions include Telerik UI for ASP.NET AJAX prior to 2026.1.421, including version 2011.2.712.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or patch has been published, users should monitor vendor communications for updates. Until a patch is available, consider implementing external controls such as network-level upload size restrictions or monitoring disk usage to mitigate potential impact.
