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
Omron CX-One CX-Programmer before 9.6, CJ2M PLC devices before 2.1, and CJ2H PLC devices before 1.5 rely on cleartext password transmission, which allows remote attackers to obtain sensitive information by sniffing the network during a PLC unlock request.
