CVE-2026-16898

Estado: En análisisAlta (7.8)—

IBM i 7.6, 7.5, 7.4, and 7.3 could allow a local authenticated attacker to change the ownership of arbitrary files due to improper validation of an attacker-controlled file path.

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.

Acceso local autenticado (AV:L/PR:L) sin interacción de usuario permite cambiar propietarios de archivos arbitrarios: escalada de privilegios (T1068). Permite manipulación de datos y propiedades de cuentas (T1565.001, T1098).

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.
