CVE-2026-44861: Arubanetworks ArubaOS SQLi Vulnerability

CVE-2026-44861 Overview

CVE-2026-44861 is a SQL injection vulnerability affecting multiple service components in HPE Aruba Networking ArubaOS. The flaw exists in backend components reachable through the AOS-8 and AOS-10 command-line interface (CLI) and management protocol. An authenticated attacker with administrative privileges can inject crafted input into parameters passed unsanitized to backend database queries. Successful exploitation leads to arbitrary command execution on the underlying operating system. The issue is tracked under [CWE-89] (Improper Neutralization of Special Elements used in an SQL Command).

Critical Impact

Authenticated administrators can pivot a SQL injection into arbitrary OS command execution on ArubaOS controllers and SD-WAN gateways, fully compromising the underlying system.

Affected Products

• HPE Aruba Networking ArubaOS (AOS-8 and AOS-10)
• HPE Aruba Networking SD-WAN
• Devices managed through the ArubaOS CLI and management protocol

Technical Details for CVE-2026-44861

Vulnerability Analysis

The vulnerability resides in several underlying service components that ArubaOS exposes through its CLI and management protocol. These components accept administrator-supplied parameters and forward them to backend database queries without proper sanitization. Because the database layer interfaces with system utilities, a crafted SQL payload escapes the query context and reaches the operating system shell. The result is arbitrary command execution in the context of the affected service. Both AOS-8 and AOS-10 code branches share the affected components, along with the ArubaOS SD-WAN product line.

Root Cause

The root cause is improper neutralization of special characters in SQL statements [CWE-89]. Service components concatenate administrator input directly into database queries instead of using parameterized statements or input validation. Because some backend queries invoke OS-level helpers, the injection extends beyond data tampering and reaches command execution.

Attack Vector

The attack vector is network-based but requires high privileges. An attacker must already hold administrative credentials on the ArubaOS device, either through legitimate access, credential theft, or chaining with a prior authentication bypass. Once authenticated, the attacker submits malicious parameters through the CLI or management protocol. The injected payload reaches the vulnerable backend query and triggers OS command execution.

No public proof-of-concept exploit is available, and the issue is not listed in the CISA Known Exploited Vulnerabilities catalog. Refer to the HPE Security Bulletin for vendor-confirmed technical detail.

Detection Methods for CVE-2026-44861

Indicators of Compromise

• Unexpected administrative CLI sessions originating from unusual source IP addresses or at atypical hours.
• ArubaOS management protocol commands containing SQL metacharacters such as single quotes, semicolons, UNION, or comment sequences (--, /*).
• New or unfamiliar OS-level processes spawned by ArubaOS database or management service accounts.
• Configuration changes or file modifications on ArubaOS controllers that do not match approved change tickets.

Detection Strategies

• Audit ArubaOS CLI and management protocol logs for input strings containing SQL injection patterns submitted to administrative endpoints.
• Correlate administrator authentications with subsequent unusual command execution or configuration export activity on the same device.
• Apply network detection signatures against ArubaOS management traffic that flag SQL keywords inside CLI parameters.

Monitoring Recommendations

• Forward ArubaOS audit logs, AAA logs, and management protocol traces to a centralized SIEM for retention and analysis.
• Alert on every successful administrative login from non-allowlisted management networks or jump hosts.
• Track the integrity of ArubaOS configuration files and flag out-of-band changes for review.

How to Mitigate CVE-2026-44861

Immediate Actions Required

• Apply the fixed ArubaOS versions identified in the HPE Security Bulletin for AOS-8, AOS-10, and SD-WAN.
• Rotate administrative credentials and TACACS/RADIUS shared secrets on affected controllers after patching.
• Restrict access to the ArubaOS CLI and management protocol to a dedicated, segmented management VLAN.
• Review recent administrative session logs and configuration diffs for evidence of exploitation.

Patch Information

HPE has published fixed ArubaOS releases for the affected AOS-8, AOS-10, and SD-WAN branches. Customers should consult the HPE Security Bulletin hpesbnw05048en_us for the specific patched version applicable to each platform and deployment model. Upgrade all controllers, mobility conductors, and SD-WAN gateways in the affected branches.

Workarounds

• Limit administrative accounts to the minimum number of trusted operators and enforce multi-factor authentication on identity providers fronting ArubaOS administration.
• Block ArubaOS management interfaces (CLI, management protocol) from untrusted networks using upstream ACLs or firewall policy.
• Disable unused management services on ArubaOS until patching is complete.
