CVE-2025-66437

Estado: AnalizadaAlta (8.8)—

An SSTI (Server-Side Template Injection) vulnerability exists in the get_address_display method of Frappe ERPNext through 15.89.0. This function renders address templates using frappe.render_template() with a context derived from the address_dict parameter, which can be either a dictionary or a string referencing an Address document. Although ERPNext uses a custom Jinja2 SandboxedEnvironment, dangerous functions like frappe.db.sql remain accessible via get_safe_globals().

Leer descripción completaMostrar menos

An authenticated attacker with permission to create or modify an Address Template can inject arbitrary Jinja expressions into the template field. By creating an Address document with a matching country, and then calling the get_address_display API with address_dict="address_name", the system will render the malicious template using attacker-controlled data. This leads to server-side code execution or database information disclosure.

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.

SSTI en ERPNext requiere autenticación (PR:L) y acceso a servicios remotos (AV:N). Impactos: ejecución de código arbitrario en servidor y acceso a datos mediante Jinja2 sandbox bypass con frappe.db.sql.

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.
