  • WID-SEC-W-2026-3284Drupal Erweiterungen: Mehrere SchwachstellenDeutsch2026-09-09csaf · cert_bundDE

    Ein Angreifer kann mehrere Schwachstellen in Drupal ausnutzen, um Datenbankinhalte zu manipulieren oder auszulesen, Zugriffsbeschränkungen und Authentifizierungsmechanismen zu umgehen, vertrauliche Informationen offenzulegen, Cross Site Scripting Angriffe auszuführen, Benutzer auf manipulierte Webseiten umzuleiten, SAML-Authentifizierungen zu beeinflussen oder wiederzuverwenden, interne Ressourcen über SSRF anzusprechen sowie unberechtigt Dateien auf den Server hochzuladen.

    This module allows you to configure your Drupal site as a SAML 2.0 Service Provider so that users can authenticate through an external identity provider. The module does not sufficiently prevent reuse of previously accepted SAML assertions. Under certain circumstances, a valid assertion may be replayed within its validity period, potentially allowing repeated authentication attempts using the same assertion. This vulnerability is mitigated by the fact that an attacker must first obtain a valid SAML assertion and can only reuse it during the assertion's validity period.
