FKIE_CVE-2026-9559

Vulnerability from fkie_nvd - Published: 2026-05-29 12:16 - Updated: 2026-07-21 12:10
Severity
9.9 (Critical) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H
Summary
A path traversal vulnerability exists in the campaign import feature of Mautic 7. When extracting uploaded ZIP files during campaign imports, a flaw in the validation logic allows file paths to escape the intended temporary directories. An authenticated user with campaign import privileges (campaign:imports:create) can write arbitrary PHP files to sensitive system directories. An attacker can exploit this to overwrite critical internal configuration or cache components, resulting in Remote Code Execution (RCE) under the context of the web server user.

Al extraer archivos ZIP subidos durante las importaciones de campa\u00f1as, un fallo en la l\u00f3gica de validaci\u00f3n permite que las rutas de archivo escapen los directorios temporales previstos. Un usuario autenticado con privilegios de importaci\u00f3n de campa\u00f1as (campaign:imports:create) puede escribir archivos PHP arbitrarios en directorios sensibles del sistema. Un atacante puede explotar esto para sobrescribir componentes cr\u00edticos de configuraci\u00f3n interna o de cach\u00e9, lo que resulta en Ejecuci\u00f3n Remota de C\u00f3digo (RCE) bajo el contexto del usuario del servidor web."
