Overview
The vulnerability identified as CVE-2025-37124 is a major cybersecurity concern affecting HPE Aruba Networking SD-WAN Gateways. Unauthenticated remote attackers can exploit this vulnerability to bypass firewall protections, potentially leading to unauthorized access and disruption of services. This vulnerability is extremely critical because it exposes internal networks to harmful traffic which can compromise system integrity and result in data leakage. The impact of this vulnerability underscores the importance of timely patching and the use of additional security measures such as Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS).

How the Exploit Works
The vulnerability stems from an oversight in the firewall rule configuration in the HPE Aruba Networking SD-WAN Gateways. This allows an unauthenticated remote attacker to send specially crafted packets that are not properly inspected or blocked by the firewall. Once these packets bypass the firewall, they can be routed through the internal network potentially leading to unauthorized access and disruption of services.
Conceptual Example Code
While the specific code to exploit this vulnerability is not disclosed, an attacker might use a crafted packet that the firewall fails to block. A conceptual example could look something like this:
POST /unprotected/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_payload": "bypass_firewall_command" }In this example, “bypass_firewall_command” would represent a command or payload that takes advantage of the vulnerability in the firewall’s rule set. This vulnerability allows the malicious payload to pass through the firewall, potentially causing unauthorized access and disruption of services.
Mitigation Guidance
Users of HPE Aruba Networking SD-WAN Gateways are urged to apply the vendor’s patch to fix this vulnerability as soon as possible. As a temporary measure, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can help mitigate the risk. However, these are not long-term solutions and can only serve as additional layers of security while a patch is being applied.
