This signature detects attempts to exploit an arbitrary file upload vulnerability in Telerik UI.
Telerik UI for ASP.NET AJAX is prone to an arbitrary file-upload vulnerability. Specifically, this issue occurs due to weak 'RadAsyncUpload' encryption in 'Telerik.Web.UI'. An attacker can exploit this issue to perform arbitrary file uploads or execute arbitrary code.
An attacker may leverage this issue to upload arbitrary files to the affected computer; this can result in arbitrary code execution within the context of the vulnerable application or privilege escalation.
- Versions prior to Telerik UI for ASP.NET AJAX 2017.2.711 and 2017.1.118 are vulnerable.
