Descriptions

An issue was discovered in flatCore before 2.0.0 build 139. A stored XSS vulnerability was identified in the prefs_smtp_psw HTTP request body parameter for the acp interface. An admin user can inject malicious client-side script into the affected parameter without any form of input sanitization. The injected payload will be executed in the browser of a user whenever one visits the affected module page.

Se detectó un problema en flatCore versiones anteriores a 2.0.0 build 139. Se identificó una vulnerabilidad de tipo XSS almacenado en el parámetro del cuerpo de una petición HTTP prefs_smtp_psw para la interfaz acp. Un usuario administrador puede inyectar un script malicioso del lado del cliente en el parámetro afectado sin ningún tipo de saneamiento de la entrada. La carga útil inyectada será ejecutada en el navegador de un usuario cada vez que visite la página del módulo afectado

flatCore CMS versions prior to 2.0.0 build 139 suffer from cross site scripting, file disclosure, and remote SQL injection vulnerabilities.
