What’s the Big Deal? Unpacking the Vulnerabilities
HPE (Hewlett-Packard Enterprise) has revealed two significant security flaws impacting their Aruba Instant On Access Points. These devices are favorites for small to medium-sized businesses due to their simple setup and powerful Wi-Fi features. However, these newly discovered issues could put your network at serious risk.
The “Hidden Key” Problem: Hardcoded Credentials (CVE-2025-37103)
Imagine a secret master key that’s built right into your Wi-Fi device, and if someone knows this key, they can bypass all your normal login safeguards. That’s essentially what “hardcoded credentials” mean. For affected Aruba Instant On Access Points, this flaw allows an attacker to completely bypass the standard authentication process and gain administrative access to your device’s web interface.
This vulnerability is rated as “critical” with a CVSS v3.1 score of 9.8 out of 10. This means it’s extremely severe and easily exploitable. With admin access, an attacker could change your Wi-Fi settings, reconfigure security protocols, install malicious software (backdoors), spy on your network traffic, or even try to spread their access to other devices on your network.
Chaining Attacks: Command Injection Flaw (CVE-2025-37102)
On top of the “hidden key” problem, there’s another high-severity vulnerability: an authenticated command injection flaw. This means that once an attacker has gained administrative access (which the hardcoded credentials make easy), they can then inject their own commands directly into the device. Think of it like being able to type secret instructions directly into the Wi-Fi router, making it do whatever they want.
This flaw, when chained with the hardcoded credentials vulnerability, allows bad actors to perform a wide range of harmful actions. They could steal sensitive data, disable your security settings, or establish a persistent presence on your network, making it harder to kick them out.

These critical security vulnerabilities affect HPE Aruba Instant On Access Points running firmware version 3.2.0.1 and older. If your small business relies on these access points for employee Wi-Fi, guest networks, or any critical operations, you need to act quickly. It’s important to note that Aruba Instant On Switches are not impacted by these specific flaws.
The vulnerabilities were discovered and reported directly to HPE by a diligent security researcher named ZZ from the Ubisectech Sirius Team. Their discovery highlights the importance of ongoing security research in keeping our digital world safe.

The Simple Fix: Update Your Firmware Immediately
Thankfully, there’s a straightforward solution to these critical flaws: update your Aruba Instant On Access Point firmware to version 3.2.1.0 or newer immediately. HPE has confirmed that there are no alternative workarounds, so patching your device is the only way to secure it.
While HPE Aruba Networking is not currently aware of any active exploitation of these flaws “in the wild,” this situation can change rapidly once vulnerabilities become public knowledge. It’s a race against time, and delaying the update leaves your network exposed to potential attacks. Don’t wait for a security incident to force your hand; proactive patching is your best defense.
Stay Secure: Update Your Devices Today
In summary, if you’re using HPE Aruba Instant On Access Points, two critical vulnerabilities could allow attackers to bypass your security and gain full control over your Wi-Fi network. The good news is that the fix is simple: upgrade your device’s firmware to version 3.2.1.0 or later as soon as possible. This small step can save you from major headaches, data breaches, and service interruptions.
