CVE-2026-15469

The use of hard-coded cryptographic key vulnerability has been identified in the mesh functionality of Deco XE75 v3, XE5300 v3.6 and WE10800 v3.6. A shared RSA-512 mesh group private key is present in the affected firmware and is used by the mesh protocol for node authentication. An attacker who obtains the firmware image and has local network access may be able to authenticate as a mesh node without possessing a device-specific credential. Successful exploitation may allow an unauthenticated adjacent attacker to impersonate a trusted mesh node and bypass mesh node authentication, which may permit unauthorized changes to device or mesh configuration, affecting confidentiality, integrity and availability.

Summary		(es) Se ha identificado el uso de una vulnerabilidad de clave criptográfica codificada de forma rígida en la funcionalidad de malla de Deco XE75 v3, XE5300 v3.6 y WE10800 v3.6. Una clave privada de grupo de malla RSA-512 compartida está presente en el firmware afectado y es utilizada por el protocolo de malla para la autenticación de nodos. Un atacante que obtiene la imagen del firmware y tiene acceso a la red local podría autenticarse como un nodo de malla sin poseer una credencial específica del dispositivo. La explotación exitosa podría permitir a un atacante adyacente no autenticado suplantar a un nodo de malla de confianza y eludir la autenticación de nodos de malla, lo que podría permitir cambios no autorizados en la configuración del dispositivo o de la malla, afectando la confidencialidad, integridad y disponibilidad.
