Unauthorized FTP access via weak passwords
Published Jun 2, 2023 · Updated Mar 5, 2025
Weak password requirements in the FTP function of all RJ71EIP91 and FX5-ENET/IP versions allow remote attackers to access the modules. The FTP function relies on passwords recoverable through dictionary guessing or interception of FTP traffic rather than enforcing resilient credentials. No prior authentication or user interaction is required, but attackers must reach the FTP service or observe its traffic; exploitation exposes FTP-accessible data.

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.
