CVE-2025-67875

Estado: AnalizadaAlta (8.5)—

ChurchCRM is an open-source church management system. A privilege escalation vulnerability exists in ChurchCRM prior to version 6.5.3. An authenticated user with specific mid-level permissions ("Edit Records" and "Manage Properties and Classifications") can inject a persistent Cross-Site Scripting (XSS) payload into an administrator's profile. The payload executes when the administrator views their own profile page, allowing the attacker to hijack the administrator's session, perform administrative actions, and achieve a full account takeover.

Leer descripción completaMostrar menos

This vulnerability is a combination of two separate flaws: an Insecure Direct Object Reference (IDOR) that allows any user to view any other user's profile, and a Broken Access Control vulnerability that allows a user with general edit permissions to modify any other user's record properties. Version 6.5.3 fixes the issue.

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.

XSS persistente (CWE-79) en perfil de administrador tras autenticación (PR:L, UI:A). El atacante inyecta payload que ejecuta en sesión admin, permitiendo secuestro de sesión y takeover de cuenta.

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.

Un usuario autenticado con permisos específicos de nivel medio ('Editar Registros' y 'Administrar Propiedades y Clasificaciones') puede inyectar una carga útil persistente de Cross-Site Scripting (XSS) en el perfil de un administrador. La carga útil se ejecuta cuando el administrador ve su propia página de perfil, permitiendo al atacante secuestrar la sesión del administrador, realizar acciones administrativas y lograr una toma de control total de la cuenta. Esta vulnerabilidad es una combinación de dos fallos separados: una Referencia Directa Insegura a Objeto (IDOR) que permite a cualquier usuario ver el perfil de cualquier otro usuario, y una vulnerabilidad de control de acceso roto que permite a un usuario con permisos de edición generales modificar las propiedades de registro de cualquier otro usuario. La versión 6.5.3 soluciona el problema."
