CVE-2018-12613

An issue was discovered in phpMyAdmin 4.8.x before 4.8.2, in which an attacker can include (view and potentially execute) files on the server. The vulnerability comes from a portion of code where pages are redirected and loaded within phpMyAdmin, and an improper test for whitelisted pages. An attacker must be authenticated, except in the "$cfg['AllowArbitraryServer'] = true" case (where an attacker can specify any host he/she is already in control of, and execute arbitrary code on phpMyAdmin) and the "$cfg['ServerDefault'] = 0" case (which bypasses the login requirement and runs the vulnerable code without any authentication).

Se ha descubierto un problema en phpMyAdmin en versiones 4.38.3x anteriores a la 4.8.2 por el cual un atacante puede incluir (ver y, potencialmente, ejecutar) archivos en el servidor. La vulnerabilidad procede de una porción de código en el que las páginas se redirigen y cargan en phpMyAdmin y se realiza una prueba inadecuada para páginas en la lista blanca. Un atacante debe estar autenticado, excepto en el caso en el que "$cfg['AllowArbitraryServer'] = true" (en el que un atacante puede especificar cualquier host que ya controle y ejecutar código arbitrario en phpMyAdmin) y en el caso "$cfg['ServerDefault'] = 0" (que omite el requisito de inicio de sesión y ejecuta el código vulnerable sin autenticación).
