CVE-2012-5786

Estado: ModificadaMedia (5.8)—

** EN DISPUTA ** El código de ejemplo wsdl_first_https en distribution/src/main/release/samples/wsdl_first_https/src/main/ en Apache CXF, posiblemente v2.6.0, no comprueba si el nombre del servidor coincide con un nombre de dominio en el Common Name (CN) del asunto o el campo subjectAltName del certificado X.509, lo que permite a atacantes man-in-the-middle falsificar servidores SSL a través de un certificado válido arbitrario. NOTA: El proveedor indica que la muestra había utilizado específicamente un flag para la omisión de comprobación del DN.

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).
