CVE-2008-2040

Estado: ModificadaAlta (7.5)—💥 Exploit

Desbordamiento de búfer basado en pila en la función HTTP::getAuthUserPass (core/common/http.cpp) en Peercast 0.1218 y gnome-peercast permite a atacantes remotos provocar una denegación de servicio (caída) y posiblemente ejecutar código arbitrario a través de una cadena de Autenticación Básica con un (1) nombre de usuario o (2) contraseñas largos.

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.
