CVE-2018-17980
Estado: ModificadaAlta (7.8)—💥 Exploit
NoMachine before 5.3.27 and 6.x before 6.3.6 allows attackers to gain privileges via a Trojan horse wintab32.dll file located in the same directory as a .nxs file, as demonstrated by a scenario where the .nxs file and the DLL are in the current working directory, and the Trojan horse code is executed. (The directory could, in general, be on a local filesystem or a network share.).
CVSS
- Versión: 3.0
- Vector: CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
- Puntuación base: 7.8
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 4.55%
- Percentil entre todas las CVEs puntuadas: 91
- 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.
