No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

A weakness has been identified in Netcore NR289-GE 1.4.5102. The affected element is the function password-check of the file /bin/boa of the component Authentication. Executing a manipulation of the argument Username can lead to stack-based buffer overflow. The attack may be launched remotely. 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.
