CVE-2026-44867: Arubanetworks ArubaOS RCE Vulnerability

CVE-2026-44867 Overview

CVE-2026-44867 is a command injection vulnerability affecting the web-based management interface of HPE Aruba Networking AOS-8 and AOS-10 Operating Systems. An authenticated remote attacker can exploit the flaw to execute arbitrary commands on the underlying operating system of affected devices. The issue is tracked under CWE-77 (Improper Neutralization of Special Elements used in a Command).

Successful exploitation grants the attacker full command execution in the context of the management plane, undermining confidentiality, integrity, and availability of the network device. The vulnerability impacts both AOS-based controllers and SD-WAN gateways used in enterprise wireless and routed deployments.

Critical Impact

Authenticated attackers can execute arbitrary operating system commands on Aruba AOS-8, AOS-10, and SD-WAN devices through the web management interface, leading to full device compromise.

Affected Products

• HPE Aruba Networking AOS-8 Operating System
• HPE Aruba Networking AOS-10 Operating System
• HPE Aruba Networking SD-WAN

Technical Details for CVE-2026-44867

Vulnerability Analysis

The vulnerability resides in the web-based management interface exposed by AOS-8 and AOS-10. Specific request parameters processed by the management plane are passed to operating system command handlers without adequate neutralization. An authenticated attacker can append shell metacharacters or additional commands to these parameters, causing the device to execute attacker-supplied instructions.

The attack vector is network-based and requires low-level authenticated access to the management interface. Successful exploitation impacts confidentiality, integrity, and availability of the device. Because the management plane typically runs with elevated privileges, command injection often yields full administrative control over routing, switching, and wireless configuration.

The Aruba SD-WAN product line shares affected code paths and is therefore exposed to the same exploitation pattern. Devices with management interfaces reachable from corporate user networks or the internet face increased risk.

Root Cause

The root cause is improper neutralization of special elements within command strings constructed by the web management interface. The application fails to validate or sanitize user-controlled input before passing it to shell or system command invocations, matching the CWE-77 pattern.

Attack Vector

An authenticated user with access to the AOS web management interface submits crafted input through a vulnerable parameter. The injected payload breaks out of the intended command context and executes arbitrary commands as the management process. No user interaction is required beyond the attacker's own authenticated session.

No public proof-of-concept exploit is available at the time of publication, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog. Detailed technical specifics are described in the HPE Security Advisory.

Detection Methods for CVE-2026-44867

Indicators of Compromise

• Unexpected processes spawned by the AOS web management service, particularly shell interpreters or network utilities invoked from non-standard parent processes.
• Anomalous outbound connections originating from Aruba controllers, gateways, or SD-WAN devices to unknown destinations.
• Unauthorized configuration changes, new administrative accounts, or modified access control lists on affected devices.

Detection Strategies

• Review AOS web management access logs for repeated requests containing shell metacharacters such as ;, |, `, $(, or && in parameter values.
• Correlate authenticated management sessions with subsequent configuration changes or device behavior anomalies.
• Ingest device syslog and audit data into a centralized analytics platform to identify post-authentication command execution patterns.

Monitoring Recommendations

• Forward AOS-8, AOS-10, and SD-WAN audit logs to a SIEM and alert on administrative actions originating from unexpected source addresses or accounts.
• Monitor management VLANs for unusual east-west traffic that could indicate lateral movement from a compromised network device.
• Track firmware versions across the fleet to ensure visibility into which devices remain unpatched.

How to Mitigate CVE-2026-44867

Immediate Actions Required

• Apply the firmware updates referenced in the HPE Security Advisory for AOS-8, AOS-10, and SD-WAN platforms.
• Restrict access to the web-based management interface to a dedicated management network or jump host.
• Rotate credentials for all administrative accounts on affected devices and review accounts for unauthorized additions.

Patch Information

HPE has published fixed firmware versions for AOS-8, AOS-10, and SD-WAN in advisory hpesbnw05048en_us. Administrators should consult the HPE Security Advisory for the specific fixed release trains that apply to each deployed platform and upgrade accordingly.

Workarounds

• Disable the web-based management interface where command-line or centralized management alternatives are available.
• Enforce access control lists that limit management interface reachability to trusted administrator workstations only.
• Require multi-factor authentication on identity providers fronting device administrative access to reduce the risk of credential compromise enabling exploitation.
