Overview
The Emerson ValveLink products have been found to be vulnerable to a significant cybersecurity issue identified as CVE-2025-46358. This vulnerability arises due to the improper use or complete lack of a necessary protection mechanism that should provide a sufficient defense against directed cyber attacks. It directly affects companies using Emerson’s ValveLink products, potentially leading to system compromise or data leakage, which could have serious financial and reputational implications.

How the Exploit Works
The exploit takes advantage of the improper or missing protection mechanism in Emerson’s ValveLink products. An attacker can craft and send specially designed network packets to the product. These packets, when processed, cause the system to behave unpredictably. This could potentially allow the attacker to gain unauthorized access to the system, compromise it, or even cause data leakage.
Conceptual Example Code
The conceptual example below demonstrates how an attacker may exploit the vulnerability, using a maliciously crafted network packet.
POST /valvelink/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "exploit_payload": "crafted_malicious_code" }The above payload, when processed by an unpatched ValveLink system, could allow an attacker to manipulate the system behaviour, leading to potential system compromise or data leakage.
Mitigation
The best mitigation approach is to apply the vendor-supplied patch immediately. If this is not possible, implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation method. However, this will not provide a comprehensive solution and the system will remain potentially vulnerable until the patch is applied.
