CVE-2012-1675

Estado: ModificadaAlta (7.5)—💥 PoC

The TNS Listener, as used in Oracle Database 11g 11.1.0.7, 11.2.0.2, and 11.2.0.3, and 10g 10.2.0.3, 10.2.0.4, and 10.2.0.5, as used in Oracle Fusion Middleware, Enterprise Manager, E-Business Suite, and possibly other products, allows remote attackers to execute arbitrary database commands by performing a remote registration of a database (1) instance or (2) service name that already exists, then conducting a man-in-the-middle (MITM) attack to hijack database connections, aka "TNS Poison."

CVSS

Versión: 2.0
Vector: AV:N/AC:L/Au:N/C:P/I:P/A:P
Puntuación base: 7.5

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 77%
Percentil entre todas las CVEs puntuadas: 100
Fecha de la puntuación: 7/10/2026

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.
