What it is about

JBoss Enterprise Application Platform ist eine skalierbare Plattform für Java-Anwendungen, inklusive JBoss Application Server, JBoss Hibernate und Boss Seam. Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in Red Hat JBoss Enterprise Application Platform ausnutzen, um einen Denial of Service Zustand herbeizuführen, Daten zu manipulieren und um weitere Angriffe wie Cache-Poisoning und Session-Hijacking durchzuführen.

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

• einen Denial of Service Zustand herbeizuführen
• Daten zu manipulieren
• weitere Angriffe wie Cache-Poisoning
• Session-Hijacking durchzuführen
