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
External input could be used on TEL-STER TelWin SCADA WebInterface to construct paths to files and directories without properly neutralizing special elements within the pathname, which could allow an unauthenticated attacker to read files on the system.
