CVE-2025-15683Network attack vector

Unauthenticated device disruption via unsafe HTTP endpoints

Published Aug 10, 2026 · Updated Aug 10, 2026

Denial of service in TBEA TLogger 2.1.0.0B0.0.0.0 and earlier allows remote attackers to reboot or reset the device via HTTP requests. The web server exposes destructive action endpoints without authentication and passes attacker-controlled parameters to sprintf() and strcat() without adequate bounds checks. No account is required; crafted requests can clear application data, reboot or reset the appliance, or cause a segmentation fault that crashes its web server.
