File read and alteration via FTP path traversal
Published Sep 14, 2026 · Updated Sep 14, 2026
Path traversal in CONTEC FLEXLAN FX-series firmware allows remote authenticated users to read or alter arbitrary server files via FTP. The FTP service accepts traversal paths without confining file operations to the intended directory. Reachability requires low-privileged FTP access; successful exploitation affects file confidentiality and integrity without a reported service interruption.
