CVE-2013-7177
Estado: ModificadaMedia (5)—
El fichero config/filter.d/cyrus-imap.conf del filtro de cyrus-imap en Fail2Ban anterior a 0.8.11 permite a atacantes remotos activar el bloqueo de direcciones IP arbitrarias a través de una dirección de e-mail manipulada que coincida con una expresión regular diseñada incorrectamente.
CVSS
- Versión: 2.0
- Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P
- Puntuación base: 5
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 3.23%
- Percentil entre todas las CVEs puntuadas: 88
- Fecha de la puntuación: 13/10/2026
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).
