Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
Description
Moxa OnCell G3100V2 devices before 2.8 and G3111, G3151, G3211, and G3251 devices before 1.7 do not properly restrict authentication attempts, which makes it easier for remote attackers to obtain access via a brute-force attack.
