CVE-2024-25611: Aruba ArubaOS RCE Vulnerability Explained

CVE-2024-25611 Overview

CVE-2024-25611 is an authenticated command injection vulnerability in the ArubaOS command line interface (CLI). An attacker with valid CLI credentials can inject shell metacharacters into vulnerable commands and execute arbitrary operating system commands as a privileged user. Successful exploitation grants full control of the underlying operating system, breaking the confidentiality, integrity, and availability of the affected device. The issue is tracked under CWE-77: Improper Neutralization of Special Elements used in a Command and is documented in the Aruba Networks Security Advisory.

Critical Impact
Authenticated attackers with CLI access can execute arbitrary commands as a privileged user on the ArubaOS underlying operating system, leading to full device compromise.

Technical Details for CVE-2024-25611

Vulnerability Analysis

The vulnerability resides in the ArubaOS CLI, where specific commands pass user-supplied arguments to the underlying operating system without proper neutralization of shell metacharacters. An authenticated administrator can craft argument strings containing command separators, backticks, or subshell syntax that the shell then interprets. The result is arbitrary command execution in the context of a privileged system user rather than execution constrained to the CLI parser.

Because exploitation requires valid authentication with high privileges, the attack surface is limited to accounts that already have CLI access. However, the impact is severe: an attacker escapes the restricted CLI shell and gains full operating system access. This enables persistence, credential theft from the device configuration, tampering with wireless network policies, and lateral movement into the managed wireless infrastructure.

Root Cause

The root cause is improper neutralization of special elements passed to a downstream command interpreter [CWE-77]. Affected CLI handlers concatenate user input into shell command strings without sanitization or safe argument passing, allowing metacharacters such as ;, |, &&, or ` to break out of the intended command context.

Attack Vector

Exploitation requires network access to the CLI, typically via SSH, and valid administrative credentials. The attacker submits a malicious argument to a vulnerable CLI command; the injected payload executes as a privileged OS user. No user interaction beyond the attacker's own session is required.

No public proof-of-concept exploit code is available. See the Aruba Networks Security Advisory ARUBA-PSA-2024-002 for vendor-supplied technical detail.

Detection Methods for CVE-2024-25611

Indicators of Compromise

Unexpected child processes spawned from ArubaOS CLI or SSH management sessions on the controller.
Outbound network connections initiated by the controller to attacker-controlled infrastructure shortly after administrator logins.
CLI audit log entries containing shell metacharacters (;, |, &&, `, $() inside command arguments.
Modifications to on-device configuration files, cron entries, or startup scripts that do not correspond to change-management records.

Detection Strategies

Forward ArubaOS syslog and CLI accounting logs to a centralized SIEM and alert on command arguments containing shell metacharacters.
Correlate administrative CLI sessions with anomalous outbound traffic from the controller management interface.
Baseline expected administrator commands and flag deviations from that baseline.

Monitoring Recommendations

Enable AAA command accounting on all ArubaOS devices and ship logs to long-term storage.
Monitor authentication logs for administrative logins from unexpected source addresses or outside change windows.
Alert on configuration changes performed outside approved maintenance windows.

How to Mitigate CVE-2024-25611

Immediate Actions Required

Apply the fixed ArubaOS versions listed in ARUBA-PSA-2024-002 to all affected controllers and Mobility Conductor instances.
Restrict CLI and management-plane access to a dedicated management network reachable only from trusted administrator hosts.
Rotate administrator credentials and audit privileged accounts that had access before patching.
Review CLI accounting logs for evidence of command injection attempts covering the period before the patch was applied.

Patch Information

Aruba Networks has released fixed ArubaOS builds for the 8.x and 10.x branches. Refer to the Aruba Networks Security Advisory ARUBA-PSA-2024-002 for the specific fixed version numbers that map to each supported release train, and upgrade to the corresponding fixed build.

Workarounds

Enable the cli-parser-enable restricted-mode setting referenced in the vendor advisory to reduce exposure until patching is complete.
Limit CLI access to a small number of named administrator accounts and enforce multi-factor authentication on the identity provider fronting SSH access.
Block management-plane access from user VLANs and the internet using ACLs on the controller and upstream firewalls.

bash

# Example: restrict SSH management access to a dedicated jump host subnet
ip access-list session mgmt-restrict
  user host <jump-host-ip> svc-ssh permit
  user any svc-ssh deny
!
interface vlan <mgmt-vlan>
  ip access-group in mgmt-restrict
