What to do

AI-suggested

  1. Immediately restrict network access to the management interfaces of Ruijie RG-BCR860 devices, limiting exposure to trusted IP addresses only.
  2. Implement strict firewall rules and network segmentation to isolate these devices from untrusted networks, including the internet.
  3. Monitor network traffic for unusual POST requests targeting the /usr/lib/lua/luci/controller/api/rcmsAPI.lua endpoint, especially those invoking action_deal_update.
  4. Employ intrusion detection/prevention systems (IDS/IPS) with signatures or heuristics to detect command injection attempts.
  5. Regularly audit device configurations and logs for signs of compromise or suspicious activity.
  6. Engage with Ruijie Networks for official patches or firmware updates addressing this vulnerability and apply them promptly once available.
  7. Consider deploying application-layer gateways or web application firewalls (WAFs) capable of filtering malicious payloads targeting the vulnerable API.
  8. 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.
