What it is about
Apache Tomcat ist ein Web-Applikationsserver für verschiedene Plattformen. Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in Apache Tomcat und Tomcat Native ausnutzen, um Informationen offenzulegen und Sicherheitsmaßnahmen 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
- Informationen offenzulegen
- Sicherheitsmaßnahmen zu umgehen
Am I affected?
Affected according to the BSI:
- Debian Linux
- Amazon Linux 2
- IBM Power Hardware Management Console
- Red Hat Enterprise Linux
- SUSE Linux
- Oracle Linux
- SUSE openSUSE
- RESF Rocky Linux
- Apache Tomcat <11.0.15
- Apache Tomcat <10.1.50
- Apache Tomcat <9.0.113
- Apache Tomcat Native <2.0.12
and 5 more
The installed version is usually shown under “Help → About” or in the device’s admin interface.
