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 Improper Authentication issue was discovered in Siemens SIMATIC CP 44x-1 RNA, all versions prior to 1.4.1. An unauthenticated remote attacker may be able to perform administrative actions on the Communication Process (CP) of the RNA series module, if network access to Port 102/TCP is available and the configuration file for the CP is stored on the RNA's CPU.
