AI-suggested

Organizations should immediately verify if KAON CG3000TC or CG3000T routers are deployed within their networks and identify firmware versions in use. The primary mitigation is to upgrade affected devices to firmware versions 1.00.67 (CG3000TC) or 1.00.27 (CG3000T) or later, which remove the hard-coded credentials. Where immediate patching is not feasible, network segmentation should be implemented to isolate vulnerable routers from critical systems and restrict remote management access. Deploy network intrusion detection systems (NIDS) to monitor for unusual command execution or unauthorized access attempts. Change default management ports and disable remote administration if not required. Additionally, organizations should audit router configurations regularly and consider replacing devices that cannot be patched promptly. Vendor communication channels should be monitored for any updates or additional patches.

Description

The firmware in KAON CG3000TC and CG3000T routers contains hard-coded credentials in clear text (shared across all routers of this model) that an unauthenticated remote attacker could use to execute commands with root privileges. This vulnerability has been fixed in firmware version: 1.00.67 for CG3000TC and 1.00.27 for CG3000T.
