CVE-2026-84408

Estado: AplazadaAlta (8.7)—

QND contains an improper access control vulnerability in a named pipe, which may allow a local attacker who is logged in to a Windows PC where the affected product's client is installed to execute arbitrary commands with SYSTEM privileges.

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:N, PR:L (red con privilegios autenticados) y acceso a named pipe local sustenta T1210. El acceso a SYSTEM privileges es T1068; ejecución de comandos arbitrarios es T1059.

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.
