CVE-2008-5552

Estado: ModificadaMedia (4.3)—

El filtro XSS (ejecución de secuencias de comandos en sitios cruzados) en Microsoft Internet Explorer 8.0 Beta 2 permite a atacantes remotos saltar el mecanismo de protección XSS y generar ataques XSS mediante una secuencia CRLF junto con una cabecera Content-Type manipulada, como se demostró por una cabecera con un valor de charset utf-7. NOTA: El fabricante mantiene que el filtro XSS de manera intencionada no intenta "abordar todas las hipótesis de ataque XSS".

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).
