CVE-2007-2446

Estado: ModificadaAlta (10)—💥 Exploit
Multiple heap-based buffer overflows in the NDR parsing in smbd in Samba 3.0.0 through 3.0.25rc3 allow remote attackers to execute arbitrary code via crafted MS-RPC requests involving (1) DFSEnum (netdfs_io_dfs_EnumInfo_d), (2) RFNPCNEX (smb_io_notify_option_type_data), (3) LsarAddPrivilegesToAccount (lsa_io_privilege_set), (4) NetSetFileSecurity (sec_io_acl), or (5) LsarLookupSids/LsarLookupSids2 (lsa_io_trans_names).
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: 78%
Percentil entre todas las CVEs puntuadas: 100
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.
