CVE-2013-4123
Estado: ModificadaMedia (5)—💥 Exploit
client_side_request.cc in Squid 3.2.x before 3.2.13 and 3.3.x before 3.3.8 allows remote attackers to cause a denial of service via a crafted port number in a HTTP Host header.
CVSS
- Versión: 2.0
- Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P
- Puntuación base: 5
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 80%
- 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.
