- Summary
- Apache Karaf: Missing authorization on the jdbc:* shell command scope allows privilege escalation to remote code execution via jdbc:ds-create
- Details
-
The jdbc shell command scope shipped no org.apache.karaf.command.acl.jdbc.cfg. Karaf's command guard (SecuredSessionFactoryImpl) treats a command with no matching ACL rule as allowed, so any authenticated shell session (including one holding only the viewer role) could run every jdbc:* command. jdbc:ds-create stores a fully attacker-controlled JDBC URL into a pax-jdbc-config factory Configuration with no validation. pax-jdbc-config reactively turns that into a live DataSource. Several JDBC drivers run code or SQL at connection time based on URL parameters (e.g. H2 INIT=RUNSCRIPT), so a viewer-level shell user could reach arbitrary code execution, bypassing the admin-role gate that already protects shell:exec. This is a privilege-escalation-to-RCE chain, not merely an "admin misconfiguration".
The same applies to jms:* shell commands.
