CVE-2007-2930

Estado: ModificadaMedia (4.3)—💥 Exploit

The (1) NSID_SHUFFLE_ONLY and (2) NSID_USE_POOL PRNG algorithms in ISC BIND 8 before 8.4.7-P1 generate predictable DNS query identifiers when sending outgoing queries such as NOTIFY messages when answering questions as a resolver, which allows remote attackers to poison DNS caches via unknown vectors. NOTE: this issue is different from CVE-2007-2926.

CVSS

Versión: 2.0
Vector: AV:N/AC:M/Au:N/C:N/I:P/A:N
Puntuación base: 4.3

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 7.58%
Percentil entre todas las CVEs puntuadas: 94
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.
