CVE-2024-38658

Estado: AplazadaAlta (7.8)—

There is an Out-of-bounds read vulnerability in V-Server (v4.0.19.0 and earlier) and V-Server Lite (v4.0.19.0 and earlier). If a user opens a specially crafted file, information may be disclosed and/or arbitrary code may be executed.

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.

Vector CVSS con AV:L, UI:R indica explotación local por usuario (archivo preparado). Out-of-bounds read permite lectura de memoria e inyección de código.

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.
