CVE-2023-22763

7.2 HIGH

📋 TL;DR

This CVE describes authenticated command injection vulnerabilities in ArubaOS command line interface that allow attackers to execute arbitrary commands as privileged users on the underlying operating system. Affected organizations are those using vulnerable Aruba networking equipment with authenticated access to the CLI.

💻 Affected Systems

Products:
  • ArubaOS
Versions: Multiple versions up to specific patched versions (check vendor advisory)
Operating Systems: ArubaOS
Default Config Vulnerable: ⚠️ Yes
Notes: Requires authenticated access to CLI. All ArubaOS deployments with vulnerable versions are affected.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete compromise of Aruba networking infrastructure, lateral movement to other systems, data exfiltration, and persistent backdoor installation.

🟠

Likely Case

Network disruption, configuration changes, credential theft, and unauthorized access to connected systems.

🟢

If Mitigated

Limited impact due to network segmentation, strong authentication controls, and restricted CLI access.

🌐 Internet-Facing: MEDIUM
🏢 Internal Only: HIGH

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: LOW

Requires authenticated access but command injection is typically straightforward once authenticated.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check Aruba advisory ARUBA-PSA-2023-002 for specific patched versions

Vendor Advisory: https://www.arubanetworks.com/assets/alert/ARUBA-PSA-2023-002.txt

Restart Required: Yes

Instructions:

1. Review Aruba advisory ARUBA-PSA-2023-002. 2. Identify affected devices. 3. Download and apply appropriate firmware patches. 4. Reboot affected devices. 5. Verify patch installation.

🔧 Temporary Workarounds

Restrict CLI Access

all

Limit CLI access to trusted administrative accounts only and implement strong authentication

Network Segmentation

all

Isolate Aruba management interfaces from general network access

🧯 If You Can't Patch

  • Implement strict access controls and multi-factor authentication for all administrative accounts
  • Monitor CLI access logs for suspicious activity and implement network segmentation

🔍 How to Verify

Check if Vulnerable:

Check ArubaOS version against vulnerable versions listed in ARUBA-PSA-2023-002 advisory

Check Version:

show version (on ArubaOS CLI)

Verify Fix Applied:

Verify ArubaOS version is updated to patched version specified in vendor advisory

📡 Detection & Monitoring

Log Indicators:

  • Unusual CLI command patterns
  • Multiple failed authentication attempts followed by successful login
  • Execution of unexpected system commands

Network Indicators:

  • Unusual outbound connections from Aruba management interfaces
  • Traffic patterns inconsistent with normal administrative activity

SIEM Query:

source="aruba_logs" AND (event_type="cli_command" AND command="*;*" OR command="*|*" OR command="*`*" OR command="*$(*")
