CVE-2019-1749
Estado: ModificadaAlta (7.4)—💥 PoC
A vulnerability in the ingress traffic validation of Cisco IOS XE Software for Cisco Aggregation Services Router (ASR) 900 Route Switch Processor 3 (RSP3) could allow an unauthenticated, adjacent attacker to trigger a reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability exists because the software insufficiently validates ingress traffic on the ASIC used on the RSP3 platform. An attacker could exploit this vulnerability by sending a malformed OSPF version 2 (OSPFv2) message to an affected device. A successful exploit could allow the attacker to cause a reload of the iosd process, triggering a reload of the affected device and resulting in a DoS condition.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H
- Puntuación base: 7.4
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.60%
- Percentil entre todas las CVEs puntuadas: 47
- Fecha de la puntuación: 7/10/2026
EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
💥 Exploits públicos
Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.

La vulnerabilidad existe debido a que el software no valida lo suficiente el tráfico entrante en el ASIC empleado en la plataforma RSP3. Un atacante podría explotar esta vulnerabilidad enviando un mensaje OSPF versión 2 (OSPFv2) mal formado a un dispositivo afectado. Su explotación con éxito podría permitir que el atacante provoque la recarga del proceso iosd, desencadenando la recarga del dispositivo afectado y resultando en una condición de denegación de servicio (DoS)."
