CVE-2026-44854: Arubanetworks ArubaOS RCE Vulnerability

CVE-2026-44854 Overview

CVE-2026-44854 is a command injection vulnerability affecting the web-based management interface of Aruba Networks AOS-8 and AOS-10 Operating Systems. An authenticated remote attacker with high privileges can exploit the flaw to upload arbitrary files to the underlying operating system. Successful exploitation can lead to remote code execution as a privileged user on affected ArubaOS and SD-WAN devices. The weakness is classified under CWE-77 (Improper Neutralization of Special Elements used in a Command).

Critical Impact

Authenticated attackers can achieve remote code execution as a privileged user on ArubaOS and SD-WAN systems, compromising network infrastructure integrity, confidentiality, and availability.

Affected Products

• Aruba Networks ArubaOS (AOS-8 and AOS-10 Operating Systems)
• Aruba Networks SD-WAN
• HPE Aruba networking devices running the affected firmware versions

Technical Details for CVE-2026-44854

Vulnerability Analysis

The vulnerability resides in the web-based management interface used to administer AOS-8 and AOS-10 Operating Systems. The interface fails to properly neutralize special elements passed to system commands, allowing attacker-controlled input to alter command execution. An authenticated attacker can leverage this weakness to write arbitrary files to the underlying operating system. Once a malicious file is placed on disk, the attacker can trigger execution paths that run code with elevated privileges. The result is full compromise of the controller or gateway managing wireless and SD-WAN traffic.

Root Cause

The root cause is improper neutralization of special elements within parameters accepted by the web management interface, consistent with CWE-77. Input received from authenticated sessions is concatenated into shell-level operations without sufficient sanitization. This permits injection of additional command tokens that the underlying OS interprets and executes.

Attack Vector

Exploitation requires network access to the web management interface and valid high-privilege credentials. After authenticating, the attacker submits crafted requests containing injected command sequences. The interface processes the input and writes files to filesystem locations chosen by the attacker. The uploaded artifacts can then be invoked to execute arbitrary code as a privileged user. No user interaction is required beyond the attacker's authenticated session. Refer to the HPE Security Advisory for vendor-confirmed technical details.

Detection Methods for CVE-2026-44854

Indicators of Compromise

• Unexpected files written to system directories on ArubaOS or SD-WAN devices, particularly outside normal configuration or log paths.
• Web management interface requests containing shell metacharacters such as ;, |, &, backticks, or $() in parameter values.
• Privileged process activity originating from the web management service shortly after administrative HTTP/HTTPS requests.
• New or modified scripts and binaries in writable filesystem locations not associated with firmware updates.

Detection Strategies

• Inspect web management interface access logs for authenticated sessions submitting requests with abnormal payloads or encoded command separators.
• Correlate administrative login events with subsequent filesystem write activity to flag suspicious sequences.
• Apply network-based signatures that match command injection patterns destined for ArubaOS management ports.

Monitoring Recommendations

• Forward ArubaOS and SD-WAN management logs to a centralized SIEM or data lake for retention and analysis.
• Alert on any new administrator account creation, privilege changes, or configuration export following management interface activity.
• Monitor outbound connections from controllers and gateways to detect post-exploitation command-and-control traffic.

How to Mitigate CVE-2026-44854

Immediate Actions Required

• Apply the fixed firmware versions identified in the HPE Security Advisory for AOS-8, AOS-10, and SD-WAN.
• Restrict access to the web management interface to a dedicated management VLAN or jump host.
• Rotate administrative credentials and audit privileged accounts for unauthorized changes.
• Review recent management interface activity for signs of exploitation prior to patching.

Patch Information

Hewlett Packard Enterprise has published remediation guidance and fixed firmware releases through the official HPE Security Advisory. Administrators should consult the advisory to identify the minimum patched version for each affected platform and schedule upgrades on all controllers, mobility gateways, and SD-WAN appliances.

Workarounds

• Disable the web-based management interface where command-line or out-of-band management is available.
• Enforce network access control lists that permit management traffic only from trusted administrative subnets.
• Require multi-factor authentication on identity providers used for ArubaOS administrative access to reduce credential compromise risk.

# Example: restrict ArubaOS web management access to a trusted management subnet
configure terminal
web-server
  mgmt-auth username/password
  ssl-protocol tlsv1.2 tlsv1.3
ip access-list session mgmt-restrict
  user host 10.10.0.0 255.255.255.0 svc-https permit
  user any svc-https deny
