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) Aruba Mobility Conductor (formerly Mobility Master); Aruba Mobility Controllers; WLAN Gateways and SD-WAN Gateways managed by Aruba Central 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.

- AOS-Wi-Fi Controllers and Campus/Remote Access Points
- Summary
- An unauthenticated Denial of Service (DoS) vulnerability exists in the Auth service accessed via the PAPI protocol provided by AOS. Successful exploitation of this vulnerability results in the ability to interrupt the normal operation of the controller.
- Remediation
- Upgrade Mobility Controllers, Mobility Conductors and Gateways to one of the following AOS versions (as applicable) to resolve all the vulnerabilities described in the details section: AOS-10.6.x.x: 10.6.0.0 and above AOS-10.5.x.x: 10.5.1.1 and above AOS-10.4.x.x: 10.4.1.1 and above AOS-8.12.x.x: 8.12.0.0 and above AOS-8.11.x.x: 8.11.2.2 and above AOS-8.10.x.x: 8.10.0.12 and above NOTE: At the time of publishing of this Revision-3 of the Security Advisory, following AOS software release trains have reached their End of Maintenance (EoM) milestone: AOS 10.6.x.x : all AOS-10.5.x.x : all AOS-8.11.x.x : all Software versions with resolution/fixes for the vulnerabilities covered above can be downloaded from the HPE Networking Support Portal. https://networkingsupport.hpe.com/home/ HPE Aruba Networking does not evaluate or patch AOSbranches that have reached their End of Maintenance (EoM) milestone.

What, why and how
An unauthenticated Denial of Service (DoS) vulnerability exists in the Auth service accessed via the PAPI protocol provided by ArubaOS. Successful exploitation of this vulnerability results in the ability to interrupt the normal operation of the controller.
What
An unauthenticated Denial of Service (DoS) vulnerability exists in the Auth service accessed via the PAPI protocol provided by ArubaOS. Successful exploitation of this vulnerability results in the ability to interrupt the normal operation of the controller.
Why
A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
How
An attacker operating through a network path 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
- a network path → Stack-based Buffer Overflow → disrupt the affected service
- 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-121 ↗
CWE-121: Stack-based Buffer Overflow. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
- 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.

- 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.
