FKIE_CVE-2026-42626

Vulnerability from fkie_nvd - Published: 2026-05-22 17:16 - Updated: 2026-07-23 16:10
Severity
5.9 (Medium) - CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L
Summary
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.

Un atacante remoto no autenticado en la misma red puede establecer una conexi\u00f3n persistente al puerto 9100 y enviar paquetes keep-alive, lo que provoca que los hilos de sesi\u00f3n de la impresora permanezcan bloqueados en un estado de espera. El firmware carece de tiempos de espera de conexi\u00f3n y l\u00edmites de sesi\u00f3n concurrentes, lo que resulta en una Denegaci\u00f3n de Servicio (DoS) persistente que deja la impresora sin respuesta a todos los comandos de usuario y trabajos de impresi\u00f3n. Se requiere intervenci\u00f3n f\u00edsica (reinicio manual) para restaurar la funcionalidad, y el ataque puede ser reiniciado inmediatamente."
