Compensating controls
- Validate the affected product branch and deploy the verified fixed release.
- Restrict the affected network interface to trusted sources where business-safe.
- Monitor vendor guidance and exploitation sources for a material change.
Verification
- Confirm that the asset runs Hewlett Packard Enterprise (HPE) ALE 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 Analytics and Location Engine (ALE)
- Summary
- Multiple vulnerabilities exist in the Analytics and Location Engine (ALE) that may allow for unauthorized access or denial of service. An unauthenticated remote attacker could exploit these vulnerabilities by sending specially crafted input or leveraging improper security configurations. Successful exploitation could result in a denial of service condition or unauthorized access to sensitive information.
- Remediation
- In order to address the vulnerabilities described in the Details Section, HPE Networking recommends upgrading the HPE Networking Analytics and Location Engine (ALE) software to the following version(s) (as applicable): - ALE 5.1.0.0 Software versions with resolution/fixes for the disclosed vulnerabilities can be downloaded from the HPE Networking Support Portal at: https://networkingsupport.hpe.com/home/.
Medium technical severity with no CISA KEV confirmation; remediate through the normal risk-based patch cycle unless local exposure raises the priority.

What, why and how
Multiple vulnerabilities exist in the Analytics and Location Engine (ALE) that may allow for unauthorized access or denial of service. An unauthenticated remote attacker could exploit these vulnerabilities by sending specially crafted input or leveraging improper security configurations. Successful exploitation could result in a denial of service condition or unauthorized access to sensitive information.
What
Multiple vulnerabilities exist in the Analytics and Location Engine (ALE) that may allow for unauthorized access or denial of service. An unauthenticated remote attacker could exploit these vulnerabilities by sending specially crafted input or leveraging improper security configurations. Successful exploitation could result in a denial of service condition or unauthorized access to sensitive information.
Why
The product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated.
How
An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may obtain information outside the intended access boundary.

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
- a network path → Allocation of Resources Without Limits or Throttling → obtain information outside the intended access boundary
- Attack surface
- Network
- 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-770 ↗
CWE-770: Allocation of Resources Without Limits or Throttling. The product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated.
- CVSS vector
?
CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity. CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:LCommon Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.
AVNetworkAttack vector: The vulnerable component can be reached over a 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.CNoneConfidentiality impact: No direct loss is represented by this metric.INoneIntegrity impact: No direct loss is represented by this metric.ALowAvailability impact: A successful attack can cause a limited 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.

Patch and workaround
Operational remediation based on structured source evidence.
- Status
?
Patch availability is based on structured fixed-version fields and authoritative update references. If no fix is verified, check the vendor advisory before making a change. - Patch available
- Action
- In order to address the vulnerabilities described in the Details Section, HPE Networking recommends upgrading the HPE Networking Analytics and Location Engine (ALE) software to the following version(s) (as applicable): - ALE 5.1.0.0 Software versions with resolution/fixes for the disclosed vulnerabilities can be downloaded from the HPE Networking Support Portal at: https://networkingsupport.hpe.com/home/.
- Workaround
- No verified workaround is recorded. If business-safe, reduce exposure to the affected interface and allow only trusted sources until authoritative guidance is available.
