Unauthorized SFTP file access via hard-coded key
Published Nov 22, 2024 · Updated Nov 22, 2024
Hard-coded cryptographic keys in Aiphone IX and IXG systems allow attackers on an adjacent network to read and alter files over SFTP. A shared key embedded in affected firmware and support software authenticates SFTP sessions without a device-specific secret. No product account is required, but adjacent-network access is required; successful login permits unauthorized file retrieval and modification.

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?
Compare these published version ranges with your installed build and any vendor patches.
