CVE-2007-1057

Estado: ModificadaMedia (6.9)—💥 Exploit

El cliente Net Direct para Linux versiones anteriores a 6.0.5 de Nortel Application Switch 2424, VPN 3050 y 3070, y SSL VPN Module 1000 extrae y ejecuta ficheros con permisos inseguros, lo cual permite a usuarios locales explotar una condición de carrera para reemplazar un fichero re-escribible en /tmp/NetClient y causar que otro usuario ejecute código de su elección cuando intenta ejecutar ese cliente, como se demuestra reemplazando /tmp/NetClient/client.

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).

💥 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.
