Estado: AnalizadaCrítica (9.8)—

An issue in the OTP mechanism of Chavara Family Welfare Centre Chavara Matrimony Site v2.0 allows attackers to bypass authentication via supplying a crafted request.

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.

Vector CVSS con AV:N/PR:N/UI:N indica explotación remota sin privilegios (T1190). CWE-287 (autenticación débil) combinado con bypass de OTP permite obtener acceso no autorizado (T1078). Confianza alta por descripción explícita de bypass de autenticación.

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.
