File deletion via USB path traversal
Published Mar 28, 2025 · Updated Mar 28, 2025
Path traversal in KDDI HGW-BL1500HM 002.002.003 and earlier allows remote authenticated users to delete device files via USB file sharing. The deletion process fails to confine a supplied pathname to the intended USB storage directory, so traversal sequences can target files elsewhere on the device. Exploitation requires low-privileged network access to the file-sharing function, and deletion of a device file can interrupt service.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
