      "value": "luci-app-banip contains a log parsing vulnerability where the awk-based parser extracts the first IPv4 address from log lines regardless of field position, allowing attackers to inject arbitrary IPs via attacker-controlled fields like usernames. An unauthenticated remote attacker can inject an IP address into the login username field, causing banIP to block the wrong target while the real attacker remains unblocked."

    {
      "lang": "es",
      "value": "luci-app-banip contiene una vulnerabilidad de análisis de registros donde el analizador basado en awk extrae la primera dirección IPv4 de las líneas de registro independientemente de la posición del campo, permitiendo a los atacantes inyectar direcciones IP arbitrarias a través de campos controlados por el atacante, como los nombres de usuario. Un atacante remoto no autenticado puede inyectar una dirección IP en el campo de nombre de usuario de inicio de sesión, haciendo que banIP bloquee el objetivo incorrecto mientras el atacante real permanece sin bloquear."
