A weakness has been identified in Netcore NBR200V2 1.3.241127.071246. Impacted is the function wan_config_set_vlan of the file /usr/bin/routerd of the component WAN VLAN Reconfiguration. Executing a manipulation of the argument vlan_wanX.ports can lead to buffer overflow. The attack may be performed from remote. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

EchelonGraph scoreLOW confidence
This critical-severity CVE scores 9.9 under the CNA's CVSS (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
