CVE-2010-4221
Estado: ModificadaAlta (10)—💥 Exploit
Multiple stack-based buffer overflows in the pr_netio_telnet_gets function in netio.c in ProFTPD before 1.3.3c allow remote attackers to execute arbitrary code via vectors involving a TELNET IAC escape character to a (1) FTP or (2) FTPS server.
CVSS
- Versión: 2.0
- Vector: AV:N/AC:L/Au:N/C:C/I:C/A:C
- Puntuación base: 10
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 91%
- Percentil entre todas las CVEs puntuadas: 100
- Fecha de la puntuación: 3/10/2026
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.
