CVE-2026-81625

Estado: AplazadaAlta (8.7)—

A remote attacker with user privileges may use a malicious or compromised NASL vulnerability test (VT) on the affected products to trigger a stack buffer overflow and gain full access on the compromised system.

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:L indica acceso remoto con privilegios de usuario; CWE-787 (buffer overflow) permite ejecución de código; el atacante logra acceso completo al sistema (escalada de privilegios implícita).

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.
