Summary

Oracle Communications: Mehrere Schwachstellen

Severity

Hoch

Scope

34 vulnerabilities in this advisory, including CVE-2023-40577.

CVE-2023-40577

In Oracle Communications existieren mehrere Schwachstellen. Durch Ausnutzung dieser Schwachstellen kann ein entfernter, anonymer oder authentisierter Angreifer die Vertraulichkeit, Integrität und Verfügbarkeit gefährden. Für die Ausnutzung einiger dieser Schwachstellen ist keine Benutzerinteraktion notwendig. Oracle veröffentlicht keine weiteren Details zu diesen Schwachstellen (außer der Information in der Risiko Matrix im Oracle Advisory zum Critical Patch Update, siehe Link unten in diesem Advisory). Aufgrund der knappen Informationslage erfolgt die Bewertung der Schadenshöhe ausschließlich auf Basis der CVSS Impact Matrix. Der Maximalwert für diese Produkte ist "HIGH" für "Confidentiality", "Integrity" und "Availability" über alle Schwachstellen aggregiert und bewirkt damit eine Bewertung mit dem Wert "HOCH" für die Schadenshöhe.

Known affected: 25 products Last affected: 4 products
