What to do
AI-suggested
- Immediately restrict network access to the affected device’s management interfaces, especially the endpoint handling get_wanobj POST requests, using firewall rules or network segmentation.
- Implement strict authentication and authorization controls to limit access to administrative functions.
- Monitor network traffic for unusual POST requests targeting /usr/lib/lua/luci/controller/admin/common.lua or the get_wanobj function, and set up alerts for suspicious activity.
- Engage with Ruijie Networks for official patches or firmware updates and apply them promptly once available.
- Conduct a thorough security audit of all Ruijie devices in the environment to identify and remediate similar vulnerabilities or misconfigurations.
- Employ intrusion detection/prevention systems (IDS/IPS) with signatures or heuristics to detect command injection attempts.
- Educate network administrators about this vulnerability and ensure incident response plans include steps for potential exploitation scenarios.
- Consider temporary device replacement or alternative solutions if patching is delayed and risk is unacceptable.
Description
OS Command Injection vulnerability in Ruijie RG-BCR RG-BCR600W allowing attackers to execute arbitrary commands via a crafted POST request to the get_wanobj in file /usr/lib/lua/luci/controller/admin/common.lua.
