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 FTP server in Pro-face GP-Pro EX EX-ED before 4.05.000, PFXEXEDV before 4.05.000, PFXEXEDLS before 4.05.000, and PFXEXGRPLS before 4.05.000 has hardcoded credentials, which makes it easier for remote attackers to bypass authentication by leveraging knowledge of these credentials.
