CVE-2026-44868: Arubanetworks ArubaOS RCE Vulnerability

CVE-2026-44868 Overview

CVE-2026-44868 is a command injection vulnerability in the web-based management interface of HPE Aruba Networking AOS-8 and AOS-10 operating systems. The flaw allows an authenticated remote attacker to inject and execute arbitrary commands on the underlying operating system of affected devices. The vulnerability is classified under CWE-77 (Improper Neutralization of Special Elements used in a Command).

Successful exploitation grants attackers the ability to run system-level commands on Aruba network infrastructure, including controllers and SD-WAN gateways. Network operations teams running AOS-8 or AOS-10 should treat this issue as a priority for patching.

Critical Impact
An authenticated attacker with network access to the management interface can execute arbitrary operating system commands, compromising confidentiality, integrity, and availability of Aruba networking infrastructure.

Technical Details for CVE-2026-44868

Vulnerability Analysis

The vulnerability resides in the web-based management interface exposed by AOS-8 and AOS-10. The interface accepts user-supplied input that is passed to underlying operating system commands without sufficient neutralization of shell metacharacters. This enables an attacker holding valid management credentials to break out of the intended command context.

Exploitation requires network reachability to the management interface and a valid authenticated session. Because the management plane typically runs with elevated privileges, injected commands execute in a high-privilege context on the controller or gateway.

The attack vector is network-based with low complexity, and exploitation does not require user interaction. The impact spans confidentiality, integrity, and availability — a compromised controller exposes configuration, credentials, and the ability to pivot into managed network segments.

Root Cause

The root cause is improper neutralization of special elements within command strings constructed from user input in the management interface [CWE-77]. Input flowing into shell or system command execution paths is not properly sanitized or parameterized, allowing metacharacters such as ;, |, &&, and backticks to alter command semantics.

Attack Vector

An attacker with low-privilege authenticated access to the AOS-8 or AOS-10 web management interface submits crafted parameters to a vulnerable endpoint. The injected payload appends or chains operating system commands that the device executes with the privileges of the management process. No user interaction is required, and the scope remains unchanged.

Verified exploitation details have not been publicly released. Refer to the HPE Support Document for vendor-provided technical context.

Detection Methods for CVE-2026-44868

Indicators of Compromise

Unexpected child processes spawned by the AOS web management daemon, particularly shells (sh, bash) or utilities such as wget, curl, nc, or tftp.
Outbound connections from controller or gateway management IPs to unfamiliar external hosts.
Web server access logs showing requests containing shell metacharacters (;, |, &, `, $()) in management API parameters.
Configuration changes or new administrative accounts on AOS devices outside change-control windows.

Detection Strategies

Review AOS audit logs for management interface activity from accounts performing unusual operations or accessing parameters they do not normally touch.
Inspect HTTP request bodies and query strings reaching the management interface for command separators and encoded equivalents.
Correlate authentication events on the management plane with subsequent process execution telemetry from network monitoring tools.

Monitoring Recommendations

Restrict management interface access to a dedicated management VLAN and monitor any access attempts from outside that segment.
Forward AOS syslog and audit data to a centralized logging platform and alert on command-injection patterns in HTTP request fields.
Track baseline behavior of administrative accounts and flag deviations such as off-hours logins or rapid sequences of configuration commands.

How to Mitigate CVE-2026-44868

Immediate Actions Required

Apply the fixed AOS-8 and AOS-10 software versions identified in the HPE Support Document.
Restrict access to the web-based management interface to trusted management networks using ACLs or firewall rules.
Rotate credentials for all administrative accounts on Aruba controllers and SD-WAN gateways after patching.
Audit existing accounts and remove any that are unused or unnecessary, enforcing least privilege for remaining administrators.

Patch Information

HPE Aruba Networking has released fixed software versions for AOS-8 and AOS-10. Administrators should consult the HPE Support Document for the exact fixed-version matrix corresponding to their deployed branch and apply upgrades through standard Aruba upgrade procedures.

Workarounds

Enable the cli-ssh-mgmt-auth and equivalent management ACL features to limit which source IPs can reach the web management interface.
Disable the web-based management interface on devices where command-line management is sufficient until patches are applied.
Enforce multi-factor authentication on accounts permitted to access the management plane to raise the bar for credentialed exploitation.

bash

  user any svc-https deny
