CVE-2004-1291

Estado: ModificadaAlta (7.5)—💥 Exploit

Buffer overflow in qwik-smtpd allows remote attackers to use the server as an SMTP spam relay via a long HELO command, which overwrites the adjacent localIP data buffer.

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: 2.46%
Percentil entre todas las CVEs puntuadas: 84
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.
