CVE-2017-8646
Microsoft Edge en Windows 10 1511, 1607, 1703, y Windows Server 2016 permite que un atacante ejecute código arbitrario en el contexto del usuario actual debido a la forma en la que los motores JavaScript del navegador de Microsoft renderizan contenido cuando gestionan objetos en la memoria. Esto también se conoce como "Scripting Engine Memory Corruption Vulnerability". Este ID CVE es exclusivo de CVE-2017-8634, CVE-2017-8635, CVE-2017-8636, CVE-2017-8638, CVE-2017-8639, CVE-2017-8640, CVE-2017-8641, CVE-2017-8645, CVE-2017-8647, CVE-2017-8655, CVE-2017-8656, CVE-2017-8657, CVE-2017-8670, CVE-2017-8671, CVE-2017-8672, y CVE-2017-8674.
CVSS
- Versión: 3.0
- Vector: CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H
- Puntuación base: 7.5
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 69%
- Percentil entre todas las CVEs puntuadas: 99
- Fecha de la puntuación: 9/10/2026
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.
- Publicado en Exploit-DB · Microsoft Edge Chakra - 'InterpreterStackFrame::ProcessLinkFailedAsmJsModule' Incorrect Usage of 'PushPopFrameHelper' (Denial of Service) (17/8/2017)
