HPE Aruba Networking EdgeConnect SD-WAN Gateway: Use of a Broken or Risky Cryptographic Algorithm
CVE-2025-37127 is a high-severity use of a broken or risky cryptographic algorithm vulnerability in HPE Aruba Networking EdgeConnect SD-WAN Gateway from Hewlett Packard Enterprise, with a CVSS 3.1 base score of 7.2 out of 10. It can be exploited with local access to the system by an attacker with administrator privileges, but only if a user takes part, for example by opening a link or file. Affected HPE Aruba Networking EdgeConnect SD-WAN Gateway versions: 9.5.0.0 through 9.5.3.6; 9.4.0.0 through 9.4.3.7. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.14% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Check which version of HPE Aruba Networking EdgeConnect SD-WAN Gateway you run against the affected versions below, and install the vendor's latest release.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.
Affected products and versions
| Vendor | Product | Affected versions | Fixed in |
|---|---|---|---|
| Hewlett Packard Enterprise | HPE Aruba Networking EdgeConnect SD-WAN Gateway | 9.5.0.0 through 9.5.3.6; 9.4.0.0 through 9.4.3.7 | Not stated |
Version data comes from the organisation that assigned the CVE. Confirm against the vendor advisory before deciding you are unaffected.
How the severity score breaks down

Official description
A vulnerability in the cryptographic logic used by HPE Aruba Networking EdgeConnect SD-WAN Gateways could allow an authenticated remote attacker to gain shell access. Successful exploitation could allow an attacker to execute arbitrary commands on the underlying operating system, potentially leading to unauthorized access and control over the affected systems.

The underlying weakness: Use of a Broken or Risky Cryptographic Algorithm
The product uses a broken or risky cryptographic algorithm or protocol.
How developers prevent this class of flaw
- Ensure that the design allows one cryptographic algorithm to be replaced with another in the next generation or version. Where possible, use wrappers to make the interfaces uniform. This will make it easier to upgrade to stronger algorithms. With hardware, design the product at the Intellectual Property (IP) level so that one cryptographic algorithm can be replaced with another in the next generation of the hardware product.
- Carefully manage and protect cryptographic keys (see CWE-320). If the keys can be guessed or stolen, then the strength of the cryptography itself is irrelevant.
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. Industry-standard implementations will save development time and may be more likely to avoid errors that can occur during implementation of cryptographic algorithms. Consider the ESAPI Encryption feature.
