Hewlett-Packard Enterprise (HPE) has disclosed a critical flaw in its Aruba Networking Private 5G Core On-Prem platform, tracked as CVE-2026-23818, that could allow attackers to steal user credentials. The issue stems from an open redirect vulnerability in the platform’s login flow, making it possible for attackers to trick users into handing over their credentials.
How the Attack Works
- Exploit vector: Maliciously crafted URL targeting authenticated users.
- Redirect: Victims are sent to an attacker-controlled server hosting a fraudulent login page.
- Deception: The fake page mimics the legitimate Aruba portal.
- Credential theft: Victims unknowingly enter their usernames and passwords, which are captured by the attacker.
- Cover-up: The fake page silently redirects back to the real login screen to avoid suspicion.
Impact
- Target environment: Enterprise private 5G networks, which handle sensitive data and critical device connectivity.
- Risk: Stolen administrative credentials could allow attackers to:
- Access the network management console.
- Alter configurations.
- Disrupt services.
- Launch deeper attacks into enterprise systems.
Mitigation
- Patch immediately: HPE has released fixes in security bulletin HPESBNW05032.
- User training: Staff should be trained to recognize suspicious links and verify URLs before entering credentials.
- Multi-factor authentication (MFA): Adds an extra layer of protection even if passwords are compromised.
- Monitoring: Watch for unusual login attempts or configuration changes in Aruba Private 5G environments.
Final Thought
This vulnerability is a textbook example of how user deception and open redirects can undermine enterprise security. In high-value environments like private 5G, credential theft can quickly escalate into full-scale network compromise. Organizations must patch promptly, enforce MFA, and strengthen user awareness to close this gap.
