Unauthenticated device compromise via undocumented remote protocol
Published Dec 1, 2022 · Updated Apr 24, 2025
Undocumented remote functions in Festo industrial devices allow remote attackers to read or alter data and interrupt operation. An undocumented protocol exposes device functions over unspecified IP ports without requiring authentication, while the vendor material does not disclose the commands or request format. Network reachability to an affected device is sufficient, and successful use can compromise stored or processed data and device availability.

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.
