Overview
CVE-2025-2794 represents a critical vulnerability located in the Kentico Xperience software. This vulnerability allows an unauthenticated attacker to exploit an unsafe reflection, thereby terminating the current process and initiating a Denial-of-Service (DoS) condition. This flaw is particularly concerning as it could potentially compromise systems or lead to data leakage.

How the Exploit Works
The exploit works by utilizing an unsafe reflection vulnerability in Kentico Xperience. An unauthenticated attacker can send a specially crafted request to the Kentico Xperience, which the system processes unsafely, leading to the termination of the current process and triggering a Denial-of-Service (DoS) condition.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited:
POST /unsafe_reflection HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_payload": "kill_process" }In this example, the attacker sends a malicious POST request to the ‘/unsafe_reflection’ endpoint, with a payload designed to trigger the unsafe reflection vulnerability (`”kill_process”`) causing the server to terminate the current process, leading to a Denial-of-Service condition.
Mitigation
Users are advised to apply the vendor patch as soon as it becomes available. As a temporary mitigation step, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can help detect and prevent exploitation of this vulnerability.
