CVE-2023-45618

8.2 HIGH

📋 TL;DR

This vulnerability in Aruba's AirWave client service allows attackers to delete arbitrary files on the operating system via the PAPI protocol. This could disrupt normal operations and compromise system integrity. Affected systems include Aruba access points managed through AirWave.

💻 Affected Systems

Products:
  • Aruba AirWave Management Platform
Versions: Multiple versions prior to 8.2.15.0
Operating Systems: Linux-based OS running AirWave
Default Config Vulnerable: ⚠️ Yes
Notes: Vulnerability exists in the AirWave client service that communicates with access points via PAPI protocol.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system compromise through deletion of critical system files, leading to denial of service, data loss, and potential follow-on attacks.

🟠

Likely Case

Service disruption and operational impact from deletion of configuration or log files, potentially requiring system restoration.

🟢

If Mitigated

Limited impact if proper network segmentation and access controls prevent unauthorized PAPI protocol access.

🌐 Internet-Facing: MEDIUM
🏢 Internal Only: HIGH

🎯 Exploit Status

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

Exploitation requires network access to the PAPI service (typically UDP 8211).

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: AirWave 8.2.15.0 and later

Vendor Advisory: https://www.arubanetworks.com/assets/alert/ARUBA-PSA-2023-017.txt

Restart Required: Yes

Instructions:

1. Download AirWave 8.2.15.0 or later from Aruba support portal. 2. Backup current configuration. 3. Apply the update following Aruba's upgrade documentation. 4. Restart AirWave services.

🔧 Temporary Workarounds

Network Segmentation

linux

Restrict access to PAPI service (UDP port 8211) to only trusted management networks.

iptables -A INPUT -p udp --dport 8211 -s TRUSTED_NETWORK -j ACCEPT
iptables -A INPUT -p udp --dport 8211 -j DROP

Service Restriction

all

Configure firewall rules to limit PAPI service exposure.

🧯 If You Can't Patch

  • Implement strict network segmentation to isolate AirWave management traffic
  • Monitor for unauthorized access attempts to UDP port 8211

🔍 How to Verify

Check if Vulnerable:

Check AirWave version via web interface (System > About) or CLI command 'amp_version'

Check Version:

ssh admin@airwave-server 'amp_version'

Verify Fix Applied:

Confirm version is 8.2.15.0 or higher and test PAPI service functionality

📡 Detection & Monitoring

Log Indicators:

  • Unusual file deletion events in system logs
  • Failed authentication attempts to PAPI service

Network Indicators:

  • Unexpected connections to UDP port 8211 from untrusted sources
  • Abnormal PAPI protocol traffic patterns

SIEM Query:

source="airwave.logs" AND (event_type="file_deletion" OR port=8211)
