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
An issue was discovered in Lantronix EDS3000PS 3.1.0.0R2. The authentication on management pages can be bypassed by appending a specific suffix to the URL and by sending an Authorization header that uses "admin" as the username.
