CVE-2016-10397

Estado: ModificadaAlta (7.5)—

En PHP, en versiones anteriores a la 5.6.28 y en versiones 7.x anteriores a la 7.0.13, la manipulación incorrecta de varios componentes URI en el analizador sintáctico de URI podría ser empleada por atacantes para omitir comprobaciones URI específicas de hostname, tal y como demuestran las entradas evil.example.com:80#@good.example.com/ y evil.example.com:80?@good.example.com/ en la función parse_url (implementadas en la función php_url_parse_ex en ext/standard/url.c).

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).
