Diese Anf\u00e4lligkeit erm\u00f6glicht es einem externen Angreifer, eine Datei an beliebiger Stelle im Dateisystem des Servers zu speichern, indem er eine speziell gestaltete HTTP-Anfrage sendet. Das Problem betrifft die Versionen 2.0.0 bis 2.3.37, 2.5.0 bis 2.5.33 und 6.0.0 bis 6.3.0.2 und tritt in Anwendungen auf, die die Komponente FileUploadInterceptor f\u00fcr Uploads verwenden.      <\/p>\n<p>Die Schwachstelle wird durch unzureichende \u00dcberpr\u00fcfung der Parameter verursacht, die beim Hochladen von Dateien \u00fcbermittelt werden. Bei Zugriff auf die Funktionen zum Hochladen von Dateien in der auf Apache Struts basierenden Web-Oberfl\u00e4che kann ein Angreifer einen Wert wie \u201e.. \/ .. \/ .. \/ .. \/ .. \/ webapps \/ ROOT\u201c angeben und die Speicherung einer Datei au\u00dferhalb des Verzeichnisses f\u00fcr hochgeladene Daten erzwingen (Exploit-Prototyp). Durch die M\u00f6glichkeit, Dateien in beliebige Teile des Dateisystems zu schreiben, k\u00f6nnen eigene Befehle ausgef\u00fchrt werden. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/de\/server\/dts-newyork\/\"   title=\"Server\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"2792\">Server<\/a>, indem er Skripte oder Konfigurationsdateien \u00fcberschreibt, soweit es die Berechtigungen des Benutzers erlauben, unter dem die Webanwendung ausgef\u00fchrt wird.
