What to do
AI-suggested
- Immediately restrict network access to the management interfaces of Ruijie RG-BCR860 devices, limiting exposure to trusted IP addresses only.
- Implement strict firewall rules and network segmentation to isolate these devices from untrusted networks, including the internet.
- Monitor network traffic for unusual POST requests targeting the /usr/lib/lua/luci/controller/api/rcmsAPI.lua endpoint, especially those invoking action_deal_update.
- Employ intrusion detection/prevention systems (IDS/IPS) with signatures or heuristics to detect command injection attempts.
- Regularly audit device configurations and logs for signs of compromise or suspicious activity.
- Engage with Ruijie Networks for official patches or firmware updates addressing this vulnerability and apply them promptly once available.
- Consider deploying application-layer gateways or web application firewalls (WAFs) capable of filtering malicious payloads targeting the vulnerable API.
- Educate network administrators about the risks and signs of exploitation to enhance incident response readiness.
Description
OS Command Injection vulnerability in Ruijie RG-BCR RG-BCR860 allowing attackers to execute arbitrary commands via a crafted POST request to the action_deal_update in file /usr/lib/lua/luci/controller/api/rcmsAPI.lua.
