CVE-2025-69809

Estado: AnalizadaCrítica (9.8)—

A write-what-where condition in p2r3 Bareiron commit 8e4d40 allows unauthenticated attackers to write arbitrary values to memory, enabling arbitrary code execution via a crafted packet.

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.

AV:N/PR:N/UI:N indica explotación remota sin autenticación (T1190). Write-what-where permite ejecución arbitraria de código (T1059) y manipulación de memoria/datos (T1565.001).

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.
