CVE-2024-53942
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary operating system commands with root privileges on affected NRadio N8-180 devices. Attackers can exploit this by sending specially crafted input to the web interface's radio configuration endpoint. Organizations using NRadio N8-180 devices with vulnerable firmware are affected.

⚠️ Risk & Real-World Impact
Worst Case
Complete device compromise allowing attacker to install persistent backdoors, pivot to internal networks, exfiltrate data, or render device inoperable.
Likely Case
Attacker gains root shell access to manipulate device configuration, intercept network traffic, or use device as foothold for further attacks.
If Mitigated
Limited impact if device is behind firewall with strict inbound rules and network segmentation prevents lateral movement.
🎯 Exploit Status
Proof of concept demonstrates blind command injection with output redirection. Exploitation requires network access to device web interface.

🔍 How to Verify
Check if Vulnerable:
Check firmware version via web interface or SSH. If version is NROS-1.9.2.n3.c5, device is vulnerable.Check Version:
ssh admin@device_ip 'cat /etc/version' or check web interface system infoVerify Fix Applied:
Verify firmware version has been updated to a version newer than NROS-1.9.2.n3.c5📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to /cgi-bin/luci/nradio/basic/radio with shell metacharacters in parameters
- System logs showing unexpected command execution
Network Indicators:
- HTTP POST requests to vulnerable endpoint containing shell commands (semicolons, pipes, backticks)
- Outbound connections from device to unexpected destinations
SIEM Query:
source="device_logs" AND (url="/cgi-bin/luci/nradio/basic/radio" AND (param="2.4 GHz" OR param="5 GHz") AND (content="|" OR content=";" OR content="`"))
