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) EdgeConnect SD-WAN Gateways 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 Networking EdgeConnect SD-WAN Gateways
- Summary
- A vulnerability in HPE Networking EdgeConnect SD-WAN Gateways could allow an unauthenticated adjacent attacker to obtain limited information from memory and disrupt the normal operation of the affected service. Successful exploitation could result in a denial of service (system crash) or the disclosure of uninitialized stack memory.
- Remediation
- To address the vulnerabilities described in the Details Section, HPE Networking recommends upgrading the HPE Networking EdgeConnect SD-WAN Gateways to the following software versions (as applicable): - ECOS 9.7.1.0 and above - ECOS 9.6.4.0 and above - ECOS 9.5.9.0 and above - ECOS 9.4.9.0 and above IMPORTANT: The HPE Networking EdgeConnect SD-WAN Orchestrator software version must be greater than or equal to the ECOS software version running on any HPE Networking EdgeConnect SD-WAN Gateways. Software versions with resolution/fixes for the vulnerabilities covered above can be downloaded from the HPE Networking Support Portal at: https://networkingsupport.hpe.com NOTE: Product software versions that have reached End of Maintenance (EoM) are presumed to be affected by the vulnerabilities unless explicitly stated otherwise and are not covered by this security advisory. For deployments running software versions that are past End of Support (EoS), HPE Networking has not assessed exposure to the vulnerabilities referenced in this advisory. As a result, such installations should be considered potentially impacted by the listed CVE. Customers are strongly encouraged to upgrade to a supported software release to ensure proper evaluation and remediation.

What, why and how
A vulnerability in HPE Networking EdgeConnect SD-WAN Gateways could allow an unauthenticated adjacent attacker to obtain limited information from memory and disrupt the normal operation of the affected service. Successful exploitation could result in a denial of service (system crash) or the disclosure of uninitialized stack memory.
What
A vulnerability in HPE Networking EdgeConnect SD-WAN Gateways could allow an unauthenticated adjacent attacker to obtain limited information from memory and disrupt the normal operation of the affected service. Successful exploitation could result in a denial of service (system crash) or the disclosure of uninitialized stack memory.
Why
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
How
An attacker operating through an adjacent network may attempt exploitation without authentication or user interaction. If successful, the issue may disrupt the affected service.

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 → Exposure of Sensitive Information to an Unauthorized Actor → disrupt the affected service
- 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-200 ↗
CWE-200: Exposure of Sensitive Information to an Unauthorized Actor. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
- CVSS vector
?
CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity. CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:HCommon Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.
AVAdjacentAttack vector: The attacker must be on an adjacent or logically close network.ACLowAttack complexity: No specialised conditions are required beyond attacker-controlled input.PRNonePrivileges required: The attacker does not need an account or existing privileges.UINoneUser interaction: No action by another user is required.SUnchangedScope: The security impact remains within the vulnerable component's authority.CLowConfidentiality impact: A successful attack can cause a limited loss.INoneIntegrity impact: No direct loss is represented by this metric.AHighAvailability impact: A successful attack can cause a major loss.- Post-exploitation / living off the land
- No specific living-off-the-land technique is confirmed in the structured sources. Monitor normal administration tools for activity inconsistent with the affected service's baseline.
