What it is about

TYPO3 ist ein freies Content-Management-System, basierend auf der Scriptsprache PHP und einer SQL-Datenbank. Über zahlreiche Extensions kann der Funktionsumfang der Core-Installation individuell erweitert werden. Ein Angreifer kann mehrere Schwachstellen in TYPO3 Extensions ausnutzen, um beliebigen Programmcode auszuführen, um einen SQL-Injection Angriff durchzuführen, um Informationen offenzulegen, und um Sicherheitsvorkehrungen zu umgehen.
