CVE-2025-6216

Estado: AnalizadaCrítica (9.8)—

Allegra calculateTokenExpDate Password Recovery Authentication Bypass Vulnerability. This vulnerability allows remote attackers to bypass authentication on affected installations of Allegra. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the password recovery mechanism. The issue results from reliance upon a predictable value when generating a password reset token. An attacker can leverage this vulnerability to bypass authentication on the application. Was ZDI-CAN-27104.

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 AV:N/AC:L/PR:N/UI:N indica acceso remoto sin autenticación: T1190. CWE-640 (predictable token) permite generar tokens de reset válidos, permitiendo acceso a cuentas ajenas (T1078) y potencialmente crearlas (T1098).

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.
