CVE-2024-1356: ArubaOS Command Injection RCE Vulnerability

CVE-2024-1356 Overview

CVE-2024-1356 is an authenticated command injection vulnerability in the ArubaOS command line interface (CLI). An authenticated attacker with high privileges can send crafted input to the CLI and execute arbitrary commands as a privileged user on the underlying operating system. The flaw is categorized under CWE-77: Improper Neutralization of Special Elements used in a Command. Aruba Networks disclosed the issue in advisory ARUBA-PSA-2024-002 and released fixed firmware for affected ArubaOS branches.

Critical Impact
Successful exploitation allows an authenticated user to break out of the ArubaOS CLI and execute arbitrary operating system commands with privileged rights, compromising confidentiality, integrity, and availability of the controller.

Affected Products

Aruba Networks ArubaOS (multiple branches identified in ARUBA-PSA-2024-002)
Aruba Mobility Conductor and Mobility Controllers running affected ArubaOS versions
SD-WAN gateways managed by affected ArubaOS releases

Technical Details for CVE-2024-1356

Vulnerability Analysis

The vulnerability is a command injection weakness reachable through the ArubaOS CLI. The CLI accepts operator input for administrative commands but fails to fully neutralize shell metacharacters before passing arguments to the underlying operating system. An authenticated user with sufficient privileges can chain additional operating system commands onto a legitimate CLI command and have them executed by the controller.

Because execution occurs in the underlying OS context rather than the restricted CLI shell, an attacker escapes the intended administrative boundary. The result is arbitrary command execution as a privileged user, which enables tampering with controller configuration, extraction of credentials, and lateral movement into the managed wireless environment.

Root Cause

The root cause is improper neutralization of special elements in command construction [CWE-77]. ArubaOS CLI handlers build operating system command strings using operator-supplied parameters without sufficient sanitization or safe argument passing. Metacharacters such as command separators are interpreted by the underlying shell, allowing injected commands to run alongside the intended one.

Attack Vector

Exploitation requires network access to the ArubaOS management interface and valid credentials with high privileges. The attack is remote over the network, requires no user interaction, and executes within a single security scope. Common exploitation paths include a compromised administrator account, credential reuse, or insider misuse. See the Aruba Networks Security Advisory ARUBA-PSA-2024-002 for the vendor description of affected CLI functions.

No public proof-of-concept or exploit code was available at the time of publication, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog. The EPSS probability is 1.24% (66.8th percentile) as of 2026-08-24.

Detection Methods for CVE-2024-1356

Indicators of Compromise

Unexpected child processes spawned from ArubaOS CLI sessions, especially shells or interpreters not associated with normal administrative activity.
CLI command history entries containing shell metacharacters such as ;, |, backticks, or $(...) embedded in arguments.
Outbound network connections from the controller management plane to unfamiliar hosts shortly after administrative logins.
New or modified files in operator-writable paths and unexplained changes to controller configuration.

Detection Strategies

Enable and centrally collect ArubaOS audit logs and CLI command accounting, then alert on commands containing shell control characters.
Correlate administrative logins with subsequent configuration changes or process activity to identify anomalous privileged sessions.
Baseline expected CLI usage per administrator and flag deviations such as commands issued at unusual times or from unusual source addresses.

Monitoring Recommendations

Forward ArubaOS syslog, TACACS+, and RADIUS accounting to a centralized analytics platform for retention and correlation.
Monitor authentication events for privileged ArubaOS accounts and alert on brute force, credential stuffing, or logins from unexpected geographies.
Track management-plane network flows and alert on new destinations initiated by the controller.

How to Mitigate CVE-2024-1356

Immediate Actions Required

Apply the fixed ArubaOS versions identified in ARUBA-PSA-2024-002 to all affected controllers and gateways.
Restrict CLI and management interface access to trusted administrative networks using access control lists and out-of-band management.
Rotate credentials for all privileged ArubaOS accounts and enforce multi-factor authentication where supported by the authentication backend.
Audit recent CLI activity for shell metacharacters or unexpected command patterns preceding the patch window.

Patch Information

Aruba Networks published fixed firmware branches in advisory ARUBA-PSA-2024-002. Administrators should review the advisory for the exact fixed versions matching their deployed ArubaOS branch and schedule upgrades on Mobility Conductors, Mobility Controllers, and SD-WAN gateways. The vendor advisory is the authoritative source for supported upgrade paths.

Workarounds

Limit CLI access to a small set of named administrators and enforce role-based access control to reduce the population of accounts that meet the high-privilege exploitation requirement.
Place the ArubaOS management interface on a dedicated management VLAN reachable only from a jump host.
Disable unused management protocols and require SSH with key-based authentication for CLI access.

bash

# Example: restrict management access to a trusted subnet
(config) # ip access-list session mgmt-restrict
(config-submgmt) # user host 10.10.10.0 255.255.255.0 svc-ssh permit
(config-submgmt) # user any any deny
(config) # firewall cp
(config-cp) # apply mgmt-restrict
