CVE-2016-5137

Estado: ModificadaMedia (4.3)—

La función CSPSource::schemeMatches en WebKit/Source/core/frame/csp/CSPSource.cpp en la implementación Content Security Policy (CSP) en Blink, como se usa en Google Chrome en versiones anteriores a 52.0.2743.82, no aplica políticas http :80 a URLs https :443 y no aplica políticas ws :80 a URLs wss :443, lo que facilita para atacantes remotos determinar si un sitio web HSTS específico ha sido visitado leyendo un reporte CSP. NOTA: esta vulnerabilidad está asociada con un cambio en la especificación despues de la resolución CVE-2016-1617.

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).
