CVE-2024-57427 - Reflektiertes Cross-Site-Scripting (XSS)

PHPJabbers Cinema Booking System v2.0 ist anfällig für reflektiertes Cross-Site-Scripting (XSS). Mehrere Endpunkte behandeln Benutzereingaben nicht ordnungsgemäß, sodass bösartige Skripte im Browser eines Opfers ausgeführt werden können. Angreifer können bösartige Links erstellen, um Sitzungscookies zu stehlen oder Phishing-Angriffe durchzuführen.

Angreifbare Parameter:

Auswirkungen:

Ein Angreifer könnte beliebigen JavaScript-Code im Browser eines Opfers ausführen, was Datendiebstahl, Session-Hijacking und Phishing-Angriffe ermöglicht. Diese Schwachstelle könnte die Sicherheit und Integrität von Benutzersitzungen und potenziell der Anwendung selbst gefährden.
