CVE-2026-64200

Estado: AnalizadaAlta (8.5)—

There is an out-of-bounds read vulnerability in DASYLab due to improper validation of user-supplied data.   This results in a read a past the end of an allocated heap buffer during string conversion.  Successful exploitation requires an attacker to get a user to open a specially crafted .DSB file.  This issue affects all versions before 2026.0.0.

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 AV:L UI:P indica ejecución en cliente: el usuario debe abrir archivo .DSB preparado. CWE-125 (out-of-bounds read) permite leer memoria heap.

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.
