CVE-2026-42626
HP ENVY 5000 series printers VERBASPP1N003.2237A.00 do not properly manage concurrent TCP connections to port 9100 (JetDirect/RAW printing). An unauthenticated remote attacker on the same network can establish a persistent connection to port 9100 and send keep-alive packets, causing the printer's session threads to remain locked in a waiting state. The firmware lacks connection timeouts and concurrent session limits, resulting in a persistent Denial of Service (DoS) that renders the printer unresponsive to all user commands and print jobs. Physical intervention (manual restart) is required to restore functionality, and the attack can be immediately re-initiated.
CVSS
- Versión: 3.1

"value": "Las impresoras HP ENVY serie 5000 VERBASPP1N003.2237A.00 no gestionan adecuadamente las conexiones TCP concurrentes al puerto 9100 (impresión JetDirect/RAW). Un atacante remoto no autenticado en la misma red puede establecer una conexión persistente al puerto 9100 y enviar paquetes keep-alive, lo que provoca que los hilos de sesión de la impresora permanezcan bloqueados en un estado de espera. El firmware carece de tiempos de espera de conexión y límites de sesión concurrentes, lo que resulta en una Denegación de Servicio (DoS) persistente que deja la impresora sin respuesta a todos los comandos de usuario y trabajos de impresión. Se requiere intervención física (reinicio manual) para restaurar la funcionalidad, y el ataque puede ser reiniciado inmediatamente."
