Introduction
Hewlett Packard Enterprise (HPE) has sounded the alarm over a newly discovered and dangerous security flaw in its Aruba Networking Private 5G Core platform. This critical vulnerability poses a significant threat to enterprises leveraging private 5G infrastructure. With the potential for unauthorized access to sensitive system files, the issue could expose private networks to serious risks unless organizations act quickly. The flaw, identified during internal penetration testing, could enable remote attackers to systematically extract confidential information through exposed APIs, underlining the growing cybersecurity challenges in advanced network environments.
Summary of the Threat ()
Hewlett Packard Enterprise has publicly disclosed a critical security vulnerability affecting its Aruba Networking Private 5G Core platform, with the flaw officially cataloged as CVE-2025-37100 and assigned a high CVSS severity rating of 7.7. Detected through internal penetration testing by HPE’s cybersecurity team, the flaw exists in specific versions of the platform ranging from 1.24.1.0 to 1.25.1.0. It stems from insecurely exposed application programming interfaces (APIs), which allow unauthorized actors to navigate the file system and download sensitive system data.
The attack mechanism enables directory traversal, allowing hackers to gain access to critical configuration files, authentication credentials, and other private operational data. According to the CVSS vector (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N), the vulnerability is exploitable remotely with minimal complexity and no user interaction, making it a prime target for cyberattacks.
Particularly concerning is the vulnerability’s impact on enterprises deploying private 5G networks, where the Aruba Private 5G Core acts as a central piece of infrastructure. If exploited, it could lead to the unauthorized collection of network configurations and user data, posing a major threat to enterprise confidentiality.
HPE has confirmed that no public exploits or discussions regarding this flaw have surfaced yet, meaning organizations still have a chance to patch their systems before widespread attacks begin. As a response, HPE has released a software update (version 1.25.1.1 or higher) to fix the issue and has advised immediate upgrades for affected systems. For those unable to update right away, HPE recommends disabling the “Terminal” service via the graphical user interface and ensuring that APIs are only accessible from within local networks. The company also stresses the importance of network access control and proactive monitoring to detect intrusion attempts early.
What Undercode Say:
This incident highlights a larger trend of growing vulnerabilities within private 5G network infrastructure. As organizations move toward more self-managed, high-speed networks, the complexity and exposure of these systems expand. The HPE Aruba vulnerability is particularly dangerous because it affects the API layer — a frequent blind spot in many enterprise architectures. APIs often serve as gateways to core services, and if left exposed or poorly authenticated, they can become pathways to critical internal resources.
The CVSS vector tells us this flaw is especially potent. It’s remotely exploitable, requires low privileges, and needs no user interaction, which are all characteristics of easily weaponizable vulnerabilities. Combined with the fact that it allows for a high confidentiality impact, this makes CVE-2025-37100 a priority-level risk for all affected organizations.
What’s equally troubling is the range of sensitive data potentially accessible. Configuration files and authentication credentials serve as the foundation of secure communication across the 5G core network. If an attacker retrieves these, they could impersonate users, modify settings, or even pivot into more critical business systems.
The timing of discovery also reflects a best-case scenario — the vulnerability was found internally, not in the wild. That gives defenders a rare head start. However, this also means companies must act before exploit kits or zero-day weaponizations start circulating in hacker forums.
HPE’s response, while responsible, does leave a few challenges for enterprise IT teams. The requirement to manually disable services or limit API access to internal networks demands a level of architectural discipline that not every business currently maintains. Smaller organizations or those with minimal IT staff might find the remediation process time-consuming or complex, which increases their exposure period.
The broader lesson here is that API security needs to become a core part of network defense strategies. Enterprises should employ rigorous API gateway filtering, enforce role-based access, and audit API behavior continuously. Additionally, the industry needs to push vendors toward adopting zero trust principles in API design — assuming every access attempt is hostile until proven otherwise.
In terms of future protection, businesses must integrate routine penetration testing, real-time anomaly detection, and automated patch management systems. This proactive approach could significantly reduce the time window between vulnerability discovery and full resolution.
Ultimately, this flaw is a wake-up call for companies deploying or managing 5G networks: even the most advanced infrastructure can have glaring weaknesses. The solution lies in vigilance, fast patch adoption, and smarter network design.
Fact Checker Results ✅
HPE officially disclosed the vulnerability on June 10, 2025 🗓️
The CVE (CVE-2025-37100) is confirmed and listed with a severity score of 7.7 🛡️
A patch is available, and no known public exploits have been reported as of today ⚙️
Prediction 🔮
If organizations delay implementing HPE’s patch or overlook the temporary mitigation steps, exploitation attempts will likely emerge within the next 3 to 6 weeks, especially as threat actors begin reverse-engineering the advisory. Expect increased activity in underground forums targeting private 5G infrastructures. Enterprises that prioritize patching, limit public API exposure, and monitor access logs aggressively will significantly reduce their risk. Looking forward, more vulnerabilities are likely to surface in 5G systems as adoption grows, making API security and network segmentation top priorities for cybersecurity planning in 2025 and beyond. 📡🧠
