CVE-2007-5256

Estado: ModificadaAlta (7.5)—💥 Exploit

Múltiples desbordamientos de búfer en FSD 2.052 d9 y anteriores, y FSFDT FSD 3.000 d9 y anteriores, permite (1) a atacantes remotos ejecutar código de su elección a través del comando HELP largo sobre TCP puerto 3010 en la función sysuser::exechelp en sysuser.cc y (2) usuarios remotos validados ejecutar código de su elección a través de comandos largos sobre puerto TCP 6809 en la función servinterface::sendmulticast en servinterface.cc, como se demostró con el comando PIcallsign.

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.
