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 IKS and EDS generate a predictable cookie calculated with an MD5 hash, allowing an attacker to capture the administrator's password, which could lead to a full compromise of the device.
