CVE-2026-29125

Estado: AnalizadaAlta (7.1)—

IDC SFX2100 Satalite Recievers set the `/etc/resolv.conf` file to be world-writable by any local user, allowing DNS resolver tampering that can redirect network communications, facilitate man-in-the-middle attacks, and cause denial of service.

CVSS

Probabilidad de explotación (EPSS)

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).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

AV:L + PR:L sin UI:R indica escalada local. CWE-732 (permisos incorrectos) + `/etc/resolv.conf` world-writable permite DNS tampering (MITM) y DoS. T1222 es cambio de permisos; T1557 por interceptación DNS; T1499.004 por negación de servicio.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
