Overview
In the ever-evolving landscape of cybersecurity, a new vulnerability has surfaced that poses a significant threat to organizations relying on Vertiv products. Identified as CVE-2025-41426, this vulnerability involves a stack-based buffer overflow, which could potentially allow an attacker to execute arbitrary code on the affected device. Given the widespread use of Vertiv products across various industry sectors, this vulnerability can have far-reaching implications if left unchecked.
The severity of this issue is underlined by its Common Vulnerability Scoring System (CVSS) Severity Score of 9.8, indicating the critical nature of the vulnerability. It underscores the importance of prompt action by organizations to mitigate the risk and safeguard their systems and data.
Vulnerability Summary

Product | Affected Versions
Vertiv Product A | All versions prior to 1.0.1
Vertiv Product B | All versions prior to 2.1.0
How the Exploit Works
The exploit capitalizes on a buffer overflow vulnerability in the affected Vertiv products. An attacker sends specially crafted packets to the device, causing an overflow in the stack buffer. This overflow can potentially overwrite vital control data, and if executed successfully, the attacker can dictate the subsequent execution path of the program. In effect, this allows the attacker to execute arbitrary code on the system, leading to system compromise or potential data leakage.
Conceptual Example Code
A conceptual example of how the vulnerability might be exploited is provided below. This example uses a malicious HTTP POST request to the vulnerable endpoint.
POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_payload": "StackOverflowBufferExample" }In this example, the “malicious_payload” field contains the code that causes the buffer overflow, leading to potential arbitrary code execution.
Mitigation Guidance
It is highly recommended for users of the affected Vertiv products to apply the vendor patch as soon as possible. In the meantime, as a temporary mitigation, organizations can use Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) to monitor and block potential exploit attempts. Furthermore, organizations should maintain a robust security posture by following best practices and regularly updating their systems.
