CVE-2023-36884
Estado: AnalizadaAlta (7.5)⚠ Explotación activa💥 PoC
Windows Search Remote Code Execution Vulnerability
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/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: 99%
- Percentil entre todas las CVEs puntuadas: 100
- Fecha de la puntuación: 29/9/2026
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).
CISA KEV — explotada activamente
- Añadida al catálogo: 17/7/2023
- Plazo de remediación: 29/8/2023
- Uso conocido en ransomware: Known
💥 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.
- Prueba de concepto en GitHub (no verificada) · Lista de pruebas de concepto en GitHub
⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
🎯 Técnicas ATT&CK
Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.
- Explotación
T1203Exploitation for Client Executionexecution85 % - Impacto principal
T1059.001PowerShellexecution90 % - Impacto secundario
T1068Exploitation for Privilege Escalationprivilege escalation75 %
Requiere interacción del usuario (UI:R) sobre Windows Search; CVSS HIGH con ejecución remota de código confirmada en KEV y ransomware activo; permite escalada de privilegios por CWE-362 (race condition).
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.
