What it is about

Apache ist ein Webserver für verschiedene Plattformen. Ein Angreifer kann mehrere Schwachstellen in Apache HTTP Server ausnutzen, um beliebigen Programmcode auszuführen, Sicherheitsmaßnahmen zu umgehen, Cross-Site-Scripting-Angriffe durchzuführen, Daten zu verändern und offenzulegen, einen Denial-of-Service-Zustand zu verursachen oder andere nicht näher definierte Angriffe durchzuführen.

Under what conditions?

The BSI does not name any particular preconditions. Exploitable remotely according to the BSI.
