Authenticated service interruption via Unix-time rollover
Published Oct 23, 2025 · Updated Oct 23, 2025
Integer overflow in Veeder-Root TLS4B Automatic Tank Gauge before 11.A allows remote authenticated users to interrupt service via system-time changes. The console's Unix-time handling wraps values beyond the 2038 epoch to December 13, 1901 instead of preserving a valid later date. Low-privileged network access is required; changing the clock can block logins, corrupt logs, break operational timers, and terminate leak detection.

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.
