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
The ArchiveService.rem service in Rockwell Automation FactoryTalk AssetCentre v10.00 and earlier exposes functions lacking proper authentication. This vulnerability may allow a remote, unauthenticated attacker to execute arbitrary SQL statements.
