CVE-2006-5444

Estado: ModificadaAlta (7.5)—💥 Exploit
Integer overflow in the get_input function in the Skinny channel driver (chan_skinny.c) in Asterisk 1.0.x before 1.0.12 and 1.2.x before 1.2.13, as used by Cisco SCCP phones, allows remote attackers to execute arbitrary code via a certain dlen value that passes a signed integer comparison and leads to a heap-based buffer overflow.
CVSS

Versión: 2.0
Vector: AV:N/AC:L/Au:N/C:P/I:P/A:P
Puntuación base: 7.5
Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 86%
Percentil entre todas las CVEs puntuadas: 100
Fecha de la puntuación: 6/10/2026
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.
