Threat Intelligence Brief
Telerik UI Padding-Oracle Bug Chained to Unauthenticated RCE — Public Exploit Released
Source: thehackernews.com
Threat Risk: High
Victim: Enterprise Organizations & Affected Platforms
Incident: Telerik UI Padding-Oracle Bug Chained to Unauthenticated RCE — Public Exploit Released
Impact: Unauthenticated remote exploitation, data theft, or compromise of exposed infrastructure.
Attacker: Active Threat Actors / Exploitation Groups
Analysis: A TantoSec proof-of-concept turns an AES-CBC “padding oracle” in Telerik UI for ASP.NET AJAX into unauthenticated remote code execution — but only against applications in a specific non-default configuration, and Progress patched the chain in July. There are no confirmed reports of exploitation in the wild.
