CVE-2025-32390

Estado: AnalizadaAlta (7)—

EspoCRM is a free, open-source customer relationship management platform. Prior to version 9.0.8, HTML Injection in Knowledge Base (KB) articles leads to complete page defacement imitating the login page. Authenticated users with the read knowledge article privilege can browse to the KB article and if they submit their credentials, they get captured in plain text. The vulnerability is allowed by overly permissive HTML editing being allowed on the KB articles. Any authenticated user with the privilege to read KB articles is impacted.

In an enterprise with multiple applications, the malicious KB article could be edited to match the login pages of other applications, which would make it useful for credential harvesting against other applications as well. Version 9.0.8 contains a patch for 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.

HTML Injection en artículos KB requiere interacción del usuario autenticado para capturar credenciales mediante página de login falsificada. CWE-74 (Improper Neutralization of Special Elements in Output) sustenta la inyección de HTML malicioso para phishing/credential capture.

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.

Antes de la versión 9.0.8, la inyección de HTML en los artículos de la Base de Conocimiento (KB) provocaba una desfiguración completa de la página, imitando la página de inicio de sesión. Los usuarios autenticados con privilegios de lectura de artículos de la KB podían acceder a ellos y, si introducían sus credenciales, estas se capturaban en texto plano. Esta vulnerabilidad se debe a la excesiva permisividad de la edición de HTML en los artículos de la KB. Cualquier usuario autenticado con privilegios de lectura de artículos de la KB se ve afectado. En una empresa con múltiples aplicaciones, el artículo malicioso de la KB podría editarse para que coincida con las páginas de inicio de sesión de otras aplicaciones, lo que también lo haría útil para la recolección de credenciales contra otras aplicaciones. La versión 9.0.8 incluye un parche para este problema."
