What to do

AI-suggested

Given the absence of official patches, European organizations should implement immediate compensating controls. First, restrict network access to the management interface of Ruijie RG-BCR860 devices, limiting it to trusted administrative hosts via firewall rules or VPNs. Employ network segmentation to isolate these devices from general user networks and sensitive systems. Monitor network traffic for unusual POST requests targeting the action_diagnosis endpoint and implement intrusion detection/prevention systems (IDS/IPS) signatures to detect and block exploitation attempts. Enforce strict authentication and authorization policies to minimize the number of users with privileges capable of triggering the vulnerable function. Regularly audit device configurations and logs for signs of compromise. Engage with Ruijie support channels to obtain updates on patches or firmware upgrades addressing this vulnerability. Finally, consider deploying endpoint detection and response (EDR) solutions on connected systems to detect lateral movement originating from compromised devices.

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_diagnosis in file /usr/lib/lua/luci/controller/admin/diagnosis.lua.
