CVE-2024-58338
📋 TL;DR
Anevia Flamingo XL 3.2.9 contains a restricted shell escape vulnerability that allows remote attackers to bypass the sandboxed environment via the traceroute command. This enables command injection leading to full root access on the device. Organizations using Anevia Flamingo XL 3.2.9 are affected.
💻 Affected Systems
- Anevia Flamingo XL
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Remote unauthenticated attacker gains full root access to the device, enabling complete system compromise, data theft, and persistent backdoor installation.
Likely Case
Remote attacker gains root shell access to the device, allowing them to modify configurations, intercept traffic, and use the device as a pivot point for further attacks.
If Mitigated
Attack is prevented through network segmentation, proper access controls, and disabling vulnerable services.
🎯 Exploit Status
Public exploit code is available on Exploit-DB (ID 51516), making this easily weaponizable by attackers with minimal technical skill.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.ateme.com
Restart Required: No
Instructions:
Check vendor website for security updates. If no patch is available, implement workarounds immediately.
🔧 Temporary Workarounds
Disable traceroute command
linuxRemove or restrict access to the traceroute command in the restricted shell environment
# Remove traceroute binary or modify shell restrictions
# chmod 000 /usr/bin/traceroute
# Or modify shell configuration to block traceroute
Network segmentation
allIsolate Anevia Flamingo XL devices from untrusted networks
# Configure firewall rules to restrict access
# iptables -A INPUT -s trusted_networks -p tcp --dport device_port -j ACCEPT
# iptables -A INPUT -p tcp --dport device_port -j DROP
🧯 If You Can't Patch
- Immediately isolate affected devices from internet and untrusted networks
- Implement strict network access controls and monitor for suspicious traceroute usage
🔍 How to Verify
Check if Vulnerable:
Check if device is running Anevia Flamingo XL version 3.2.9 and test if traceroute command can be used to execute arbitrary commands in restricted shell
Check Version:
# Check device version through web interface or CLI
Verify Fix Applied:
Verify traceroute command is no longer accessible or cannot be used for command injection in restricted shell
