What to do
AI-suggested
Immediate mitigation steps include restricting network access to the management interface of the affected routers, ideally limiting it to trusted internal IP addresses only. Implement strict firewall rules to block unauthorized POST requests targeting the vulnerable endpoint. Network segmentation should be enforced to isolate these devices from critical systems. Monitor network traffic for unusual POST requests or command execution patterns related to /usr/local/lua/dev_sta/networkConnect.lua. Since no official patches are available, consider deploying intrusion detection/prevention systems (IDS/IPS) with custom signatures to detect exploitation attempts. Engage with Ruijie support for firmware updates or advisories and plan for prompt patch deployment once available. Additionally, conduct regular audits of device configurations and logs to detect potential compromise early.
Description
