In dem WordPress-Plugin Ninja Forms, das mehr als eine Million aktive Installationen hat, wurde eine kritische Sicherheitsanf\u00e4lligkeit festgestellt (CVE bisher nicht vergeben), die es unbefugten Besuchern erm\u00f6glicht, die volle Kontrolle \u00fcber die Website zu erlangen. Das Problem wurde in den Versionen 3.0.34.2, 3.1.10, 3.2.28, 3.3.21.4, 3.4.34.2, 3.5.8.4 und 3.6.11 behoben. Es wird berichtet, dass die Sicherheitsanf\u00e4lligkeit bereits f\u00fcr Angriffe ausgenutzt wird. Um die Problematik schnell zu adressieren, haben die Entwickler der Plattform WordPress eine zwangsweise automatische Installation des Updates auf den Websites der Nutzer initiiert. <\/p>\n

Die Sicherheitsanf\u00e4lligkeit resultiert aus einem Fehler in der Implementierung der Merge Tags-Funktionalit\u00e4t, die es nicht authentifizierten Benutzern erm\u00f6glicht, bestimmte statische Methoden aus verschiedenen Klassen von Ninja Forms aufzurufen (die Funktion is_callable() wurde verwendet, um die Erw\u00e4hnung von Methoden in den \u00fcber Merge Tags \u00fcbergebenen Daten zu \u00fcberpr\u00fcfen). Unter anderem war der Aufruf einer Methode m\u00f6glich, die die Deserialisierung des vom Benutzer \u00fcbergebenen Inhalts durchf\u00fchrt. Durch die \u00dcbermittlung speziell gestalteter serialisierter Daten konnte ein Angreifer seine eigenen Objekte einschleusen und die Ausf\u00fchrung von PHP-Code erzielen.
