CVE-2026-22323

A CSRF vulnerability in the Link Aggregation configuration interface allows an unauthenticated remote attacker to trick authenticated users into sending unauthorized POST requests to the device by luring them to a malicious webpage. This can silently alter the device’s configuration without the victim’s knowledge or consent. Availability impact was set to low because after a successful attack the device will automatically recover without external intervention.

Summary		(es) Una vulnerabilidad CSRF en la interfaz de configuración de Agregación de Enlaces permite a un atacante remoto no autenticado engañar a usuarios autenticados para que envíen solicitudes POST no autorizadas al dispositivo atrayéndolos a una página web maliciosa. Esto puede alterar silenciosamente la configuración del dispositivo sin el conocimiento o consentimiento de la víctima. El impacto en la disponibilidad se estableció en bajo porque después de un ataque exitoso el dispositivo se recuperará automáticamente sin intervención externa.
