CVE-2014-8517
Estado: ModificadaAlta (7.5)—💥 Exploit
La función fetch_url ubicada en usr.bin/ftp/fetch.c en thftp, usada en NetBSD 5.1 en 5.1.4, 5.2 hasta 5.2.2, 6.0 hasta 6.0.6 y 6.1 hasta 6.1.5 permite a atacantes remotos ejecutar comandos arbitrarios a través de un carácter '|' (tubería) al final de una redirección HTTP.
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: 69%
- Percentil entre todas las CVEs puntuadas: 99
- Fecha de la puntuación: 8/10/2026
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.
