CVE-2017-20245

Estado: AplazadaAlta (8.8)—

Wow Viral Signups 2.1 WordPress plugin contains an SQL injection vulnerability that allows unauthenticated attackers to extract database information by exploiting the unescaped 'idsignup' POST parameter. Attackers can send crafted requests to the admin-ajax.php endpoint with malicious SQL payloads in the 'idsignup' parameter to read arbitrary data from the database.

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).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

SQL injection en parámetro POST sin autenticación a endpoint web (admin-ajax.php) permite lectura de datos de BD (CWE-89, CVSS AV:N/PR:N). Manipulación de datos es especulativa sin evidencia explícita.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
