CVE-2024-52912

Estado: AnalizadaAlta (7.5)—

Bitcoin Core before 0.21.0 allows a network split that is resultant from an integer overflow (calculating the time offset for newly connecting peers) and an abs64 logic bug.

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.

Vulnerabilidad remota de red (AV:N, PR:N, UI:N) en Bitcoin Core causada por desbordamiento de enteros; permite causador de partición de red/DoS sin privilegios: T1190 (explotación de aplicación expuesta), impacto T1499.004 (DoS de protocolos de red P2P).

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.
