CVE-2024-31483
📋 TL;DR
An authenticated sensitive information disclosure vulnerability in the CLI service accessed via PAPI protocol allows attackers to read arbitrary files on the underlying operating system. This affects ArubaOS and HPE Aruba Networking products where an authenticated user can exploit the vulnerability to access sensitive system files.
💻 Affected Systems
- ArubaOS
- HPE Aruba Networking products

⚠️ Risk & Real-World Impact
Worst Case
Attackers could read sensitive configuration files, password hashes, SSH keys, or other critical system files, potentially leading to full system compromise.
Likely Case
Authenticated users reading configuration files, logs, or other sensitive data they shouldn't have access to.
If Mitigated
Limited to authenticated users only, with proper access controls preventing unauthorized authentication.
🎯 Exploit Status
Requires authenticated access but once authenticated, exploitation appears straightforward
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisories for specific patched versions
Vendor Advisory: https://support.hpe.com/hpesc/public/docDisplay?docId=hpesbnw04647en_us&docLocale=en_US
Restart Required: Yes
Instructions:
1. Review vendor advisories for affected versions. 2. Apply recommended patches from HPE/Aruba. 3. Restart affected services/systems. 4. Verify patch application.
🔧 Temporary Workarounds
Restrict PAPI Access
allLimit access to PAPI protocol to trusted networks only
Configure firewall rules to restrict PAPI port access
Implement network segmentation for management interfaces
Strengthen Authentication
allImplement strong authentication mechanisms and limit CLI access
Enable multi-factor authentication
Implement role-based access controls
Regularly audit user accounts
🧯 If You Can't Patch
- Implement strict network segmentation to isolate management interfaces
- Enforce principle of least privilege for CLI access and regularly audit user permissions
🔍 How to Verify
Check if Vulnerable:
Check if running affected ArubaOS versions and if PAPI service is accessibleCheck Version:
show version (on Aruba devices)Verify Fix Applied:
Verify patch version against vendor advisory and test that file read attempts via PAPI are blocked📡 Detection & Monitoring
Log Indicators:
- Unusual file access patterns via CLI
- Multiple failed authentication attempts followed by successful access
- Unexpected file read operations
Network Indicators:
- Unusual PAPI protocol traffic patterns
- File read requests via management interfaces
