CVE-2026-35098

KTM System e-BOK does not implement any limit or timeout on consecutive login attempts, allowing an attacker to perform unlimited authentication requests. This lack of rate‑limiting enables efficient brute‑force attacks against user accounts. When combined with vulnerability CVE-2026-35097, where passwords are restricted to a six‑digit numeric format, this becomes a critical issue, as such passwords can be brute‑forced in a relatively short time. This issue was fixed in the patch published in June 2026.

Summary		(es) KTM System e-BOK no implementa ningún límite o tiempo de espera en los intentos de inicio de sesión consecutivos, permitiendo a un atacante realizar solicitudes de autenticación ilimitadas. Esta falta de limitación de velocidad permite ataques de fuerza bruta eficientes contra las cuentas de usuario. Cuando se combina con la vulnerabilidad CVE-2026-35097, donde las contraseñas están restringidas a un formato numérico de seis dígitos, esto se convierte en un problema crítico, ya que dichas contraseñas pueden ser forzadas por fuerza bruta en un tiempo relativamente corto. Este problema fue solucionado en el parche publicado en junio de 2026.
