Ein Angreifer kann mehrere Schwachstellen in Strapi ausnutzen, um einen Denial-of-Service-Zustand herbeizuführen, Administratorrechte zu erlangen, Daten zu manipulieren, vertrauliche Informationen offenzulegen oder 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
- einen Denial-of-Service-Zustand herbeizuführen
