Summary

MediaWiki: Mehrere Schwachstellen

Severity

Hoch

Scope

9 vulnerabilities in this advisory, including CVE-2021-44854.

CVE-2021-44854

In verschiedenen MediaWiki Extensions und Skins existieren mehrere Schwachstellen. Die Fehler bestehen aufgrund mehrerer XSS-Schwachstellen, eines CSRF-Problems, mehrerer Zeitüberschreitungen, sowie Problemen bei der Verwaltung von Gruppen, Cachedaten oder Filterkonfigurationen. Ein entfernter anonymer oder authentisierter Angreifer kann diese Schwachstellen ausnutzen, um einen Denial-of-Service-Zustand zu verursachen, einen Cross-Site-Scripting-Angriff durchzuführen, vertrauliche Informationen offenzulegen und Sicherheitsmaßnahmen zu umgehen. Die erfolgreiche Ausnutzung einiger dieser Schwachstellen erfordert eine Benutzerinteraktion und erhöhte Berechtigungen.

Known affected: 2 products
