CVE-2017-7272

Estado: ModificadaAlta (7.4)—

PHP hasta la versión 7.1.11 podría permitir SSRF en aplicaciones que aceptan un argumento de nombre de host fsockopen o pfsockopen con la expectativa de que el número de puerto esté limitado. Debido a que se reconoce una sintaxis :port, fsockopen empleará el número de puerto especificado en el argumento del nombre de host en lugar del número de puerto en el segundo argumento de la función.

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).
