CVE-2025-43973

Estado: AnalizadaCrítica (9.8)—

An issue was discovered in GoBGP before 3.35.0. pkg/packet/rtr/rtr.go does not verify that the input length corresponds to a situation in which all bytes are available for an RTR message.

CVSS

Probabilidad de explotación (EPSS)

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).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

GoBGP expuesto en red (AV:N, PR:N) sin interacción permite DoS por lectura de longitud no verificada en RTR; CWE-193 es buffer over-read que causa crashs y potencial exfiltración de memoria.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
