Cierto componente de depuración en IBM AIX v5.3 y v6.1 no proporciona la gestión de los entornos (1) _LIB_INIT_DBG y (2) _LIB_INIT_DBG_FILE, que permite a usuarios locales obtener privilegios utilizando para ello un programa setuid-root para crear un archivo root-owned a su elección con permisos world-writable, relacionados con ibC.a (como la librería XL C++ runtime) en AIX v5.3 y libc.a en AIX v6.1.

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).

Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
