CVE-2024-42503
📋 TL;DR
This CVE describes an authenticated command injection vulnerability in ArubaOS CLI that allows authenticated attackers to execute arbitrary commands with privileged user permissions on the underlying operating system. It affects Aruba networking devices running vulnerable versions of ArubaOS. Attackers need valid credentials to exploit this vulnerability.
💻 Affected Systems
- ArubaOS
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

- Review the CVE details at NVD
- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to gain root-level access, install persistent backdoors, steal sensitive data, pivot to other network segments, and disrupt network operations.
Likely Case
Privilege escalation leading to unauthorized configuration changes, network reconnaissance, credential harvesting, and potential lateral movement within the network.
If Mitigated
Limited impact due to strong access controls, network segmentation, and monitoring that would detect unusual CLI activity.
🎯 Exploit Status
Requires authenticated access to the CLI. Attack complexity is low once authentication is obtained. No public exploit code identified in the provided reference.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific fixed versions
Vendor Advisory: https://support.hpe.com/hpesc/public/docDisplay?docId=hpesbnw04709en_us&docLocale=en_US
Restart Required: Yes
Instructions:
1. Review the HPE Aruba advisory for affected versions. 2. Download and apply the appropriate firmware update from HPE/Aruba support portal. 3. Schedule maintenance window for device reboot. 4. Verify the update was successful and test functionality.
🔧 Temporary Workarounds
Restrict CLI Access
allLimit CLI access to only necessary administrative users and implement strong authentication controls
configure terminal
aaa authentication login default local
aaa authorization exec default local
username admin privilege 15 secret strongpassword
Network Segmentation
allIsolate management interfaces from untrusted networks and implement strict firewall rules
🧯 If You Can't Patch
- Implement strict access controls and multi-factor authentication for all administrative accounts
- Monitor CLI logs for unusual command execution patterns and implement network segmentation
🔍 How to Verify
Check if Vulnerable:
Check ArubaOS version via CLI: 'show version' and compare against vendor advisory for affected versionsCheck Version:
show versionVerify Fix Applied:
After patching, verify the firmware version has been updated and test that command injection attempts are properly sanitized📡 Detection & Monitoring
Log Indicators:
- Unusual CLI command sequences
- Multiple failed authentication attempts followed by successful login
- Execution of system-level commands from CLI
Network Indicators:
- Unusual SSH/Telnet traffic to management interfaces
- Unexpected outbound connections from network devices
