What it is about

Der PostgreSQL JDBC Driver ermöglicht Java-Anwendungen die Verbindung und Interaktion mit PostgreSQL-Datenbanken. Ein entfernter, anonymer Angreifer kann eine Schwachstelle in PostgreSQL JDBC Driver ausnutzen, um Sicherheitsvorkehrungen zu umgehen.

Under what conditions?

Over the network and without logging in. This is the most dangerous combination: attackers can scan reachable devices automatically.

What can happen in the worst case

An attacker could use the vulnerability to

  • Sicherheitsvorkehrungen zu umgehen
