Compensating controls
- Validate the affected product branch and deploy the verified fixed release.
- Restrict local access and enforce least privilege on affected hosts.
- Monitor vendor guidance and exploitation sources for a material change.
Verification
- Confirm that the asset runs Hewlett Packard Enterprise (HPE) HPE Aruba Networking Private 5G Core and falls inside the recorded affected range.
- Verify the installed build against the product-specific fixed version after deployment.
- Validate exposure, authentication requirements and compensating controls in the actual environment.
- Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.

The vendor explicitly identifies these products as affected by this CVE.
- HPE Aruba Networking Private 5G Core
- Summary
- An authentication bypass in the application API allows an unauthorized administrative account to be created. A remote attacker could exploit this vulnerability to create privileged user accounts. Successful exploitation could allow an attacker to gain administrative access, modify system configurations, and access or manipulate sensitive data.
- Remediation
- To resolve the vulnerabilities described above, it is recommended to upgrade the software to HPE Aruba Networking Private 5G Core 1.25.1.0 and above. The latest version of the product is available for download at https://myenterpriselicense.hpe.com/. HPE Aruba Networking does not evaluate or patch HPE Aruba Networking Private 5G Core Software versions that have reached their End of Support (EoS) milestone.

What, why and how
An authentication bypass in the application API allows an unauthorized administrative account to be created. A remote attacker could exploit this vulnerability to create privileged user accounts. Successful exploitation could allow an attacker to gain administrative access, modify system configurations, and access or manipulate sensitive data.
What
An authentication bypass in the application API allows an unauthorized administrative account to be created. A remote attacker could exploit this vulnerability to create privileged user accounts. Successful exploitation could allow an attacker to gain administrative access, modify system configurations, and access or manipulate sensitive data.
Why
The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
How
An attacker operating through an adjacent network may attempt exploitation without authentication or user interaction. If successful, the issue may bypass an access boundary or take over an account.

Exploit reality and attack path
CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
Observed exploitation No confirmed evidence
?
Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
Public PoC / exploit material None recorded
?
Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
- Likely attack path
- an adjacent network → Improper Access Control → bypass an access boundary or take over an account
- Attack surface
- Adjacent
- Privileges required
- None: unauthenticated exploitation is possible
- User interaction
- None
- Attack complexity
- Low: no specialised conditions are recorded
- Security boundary
- Unchanged: impact remains within the vulnerable component's security authority
- Weakness
?
CWE means Common Weakness Enumeration: a standard category for the underlying weakness. - CWE-284 ↗
CWE-284: Improper Access Control. The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
