Authentication bypass via web-server buffer over-read
Published Feb 13, 2025 · Updated Feb 13, 2025
Buffer over-read in the Zettler 130.8005 TCP/IP Gateway web server firmware 12h allows remote attackers to steal session tokens. The web server returns data beyond its intended response buffer, exposing process-memory garbage that includes a logged-in user's token. No attacker credentials are required, but a legitimate user must be logged in; the stolen token permits post-authentication API calls within that user's permissions.

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.
