Hiervon betroffen ist ein unbekannter Codeblock der Datei /boafrm/formIPv6Addr der Komponente HTTP POST Request Handler. Durch das Manipulieren des Arguments submit-url mit unbekannten Daten kann eine buffer overflow-Schwachstelle ausgenutzt werden. Der Angriff kann \u00fcber das Netzwerk angegangen werden. Der Exploit steht zur \u00f6ffentlichen Verf\u00fcgung."
