Descriptions

An issue was discovered in flatCore before 2.0.0 build 139. A local file disclosure vulnerability was identified in the docs_file HTTP request body parameter for the acp interface. This can be exploited with admin access rights. The affected parameter (which retrieves the contents of the specified file) was found to be accepting malicious user input without proper sanitization, thus leading to retrieval of backend server sensitive files, e.g., /etc/passwd, SQLite database files, PHP source code, etc.

Se detectó un problema en flatCore versiones anteriores a 2.0.0 compilación 139. Se identificó una vulnerabilidad de divulgación de archivos locales en el parámetro del cuerpo de una petición HTTP docs_file body para la interfaz acp. Esto puede ser explotado con derechos de acceso de administrador. Se encontró que el parámetro afectado (que recupera el contenido del archivo especificado) acepta la entrada de usuarios maliciosos sin un saneamiento apropiado, conllevando entonces a una recuperación de archivos confidenciales del servidor del backend, por ejemplo, /etc/passwd, archivos de la base de datos SQLite, código fuente PHP, etc

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