What to do
AI-suggested
- Immediately restrict access to the management interfaces of Ruijie RG-EW1200G PRO devices to trusted IP addresses and networks, ideally isolating them from the public internet.
- Implement network segmentation to limit the exposure of vulnerable devices and reduce lateral movement opportunities.
- Monitor network traffic for unusual POST requests targeting the /usr/local/lua/dev_config/config_retain.lua module_set endpoint, using IDS/IPS or custom detection rules.
- Apply vendor-supplied patches or firmware updates as soon as they become available; in the absence of patches, consider temporary device replacement or removal from critical network segments.
- Enforce strict input validation and command execution policies on affected devices if configurable.
- Conduct regular vulnerability scans and penetration tests focusing on Ruijie devices to identify potential exploitation attempts.
- Educate network administrators about this vulnerability and the importance of monitoring and access controls.
- Maintain up-to-date asset inventories to quickly identify and remediate affected devices.
