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) AOS-8 Instant and AOS-10 AP 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.

ARUBA-PSA-2024-006 · CSAF 2.0 · revision 1 · finalHPE Aruba NetworkingUnauthenticated Buffer Overflow Vulnerability in the Simultaneous Authentication of Equals (SAE) Service Accessed by the PAPI Protocol
The vendor explicitly identifies these products as affected by this CVE.
- Aruba InstantOS and Aruba Access Points running ArubaOS 10
- Summary
- There is a buffer overflow vulnerability in the underlying SAE (Simultaneous Authentication of Equals) service that could lead to unauthenticated remote code execution by sending specially crafted packets destined to the PAPI (Aruba's Access Point management protocol) UDP port (8211). Successful exploitation of this vulnerability results in the ability to execute arbitrary code as a privileged user on the underlying operating system.
- Remediation
- To address the vulnerabilities described above for the affected release branches, it is recommended to upgrade the software to the following versions: - ArubaOS 10.6.x.x: 10.6.0.0 and above - ArubaOS 10.5.x.x: 10.5.1.1 and above - ArubaOS 10.4.x.x: 10.4.1.1 and above - InstantOS 8.12.x.x: 8.12.0.0 and above - InstantOS 8.11.x.x: 8.11.2.2 and above - InstantOS 8.10.x.x: 8.10.0.11 and above - InstantOS 8.6.x: 8.6.0.24 and above HPE Aruba Networking does not evaluate or patch InstantOS and ArubaOS 10 software branches that have reached their End of Maintenance (EoM) milestone.

What, why and how
There is a buffer overflow vulnerability in the underlying SAE (Simultaneous Authentication of Equals) service that could lead to unauthenticated remote code execution by sending specially crafted packets destined to the PAPI (Aruba's Access Point management protocol) UDP port (8211). Successful exploitation of this vulnerability results in the ability to execute arbitrary code as a privileged user on the underlying operating system.
What
There is a buffer overflow vulnerability in the underlying SAE (Simultaneous Authentication of Equals) service that could lead to unauthenticated remote code execution by sending specially crafted packets destined to the PAPI (Aruba's Access Point management protocol) UDP port (8211). Successful exploitation of this vulnerability results in the ability to execute arbitrary code as a privileged user on the underlying operating system.
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 execute code or commands in the affected security context.

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 → execute code or commands in the affected security context
- Attack surface
- Network
- Privileges required
- None: unauthenticated exploitation is possible
- User interaction

- Low: no specialised conditions are recorded

- 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:H/I:H/A:HCommon Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.

- After compromise, an attacker may use built-in shells, scripting engines, scheduled tasks and native network utilities for discovery, persistence or movement. This is a plausible LoTL path, not evidence that it has occurred for every attack.
