CVE-2025-22881

Estado: AnalizadaAlta (8.4)—

Delta Electronics CNCSoft-G2 lacks proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. If a target visits a malicious page or opens a malicious file an attacker can leverage this vulnerability to execute code in the context of the current process.

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 con UI:A (interacción del usuario) indica explotación en cliente (abrir archivo malicioso). Desbordamiento de búfer en heap permite ejecución de código arbitrario en el proceso.

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.
