What it is about
Drupal 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 Drupal ausnutzen, um Informationen offenzulegen, Daten zu manipulieren und Sicherheitsmaßnahmen zu umgehen.
Under what conditions?
The BSI does not name any particular preconditions. Exploitable remotely according to the BSI.
What can happen in the worst case
An attacker could use the vulnerability to
- Informationen offenzulegen
- Daten zu manipulieren
- Sicherheitsmaßnahmen zu umgehen
