CVE-2023-32164Network attack vector

Unauthenticated file disclosure via unchecked TFTP path

Published May 3, 2024 · Updated Sep 18, 2024

Path traversal in D-Link D-View 8 2.0.1.27 and earlier allows remote attackers to read sensitive files without authentication. The TftpSendFileThread class uses a user-supplied path in file operations without validating that the resolved path remains within an authorized directory. A network request can therefore retrieve files accessible to the D-View service running as SYSTEM, while no data modification or service interruption is reported.
