CVSS: 6.5EPSS: 0%CPEs: 2EXPL: 0CVE-2024-31141 – Apache Kafka Clients: Privilege escalation to filesystem read-access via automatic ConfigProvider
https://notcve.org/view.php?id=CVE-2024-31141
Files or Directories Accessible to External Parties, Improper Privilege Management vulnerability in Apache Kafka Clients. Apache Kafka Clients accept configuration data for customizing behavior, and includes ConfigProvider plugins in order to manipulate these configurations. Apache Kafka also provides FileConfigProvider, DirectoryConfigProvider, and EnvVarConfigProvider implementations which include the ability to read from disk or environment variables. In applications where Apache Kafka Clients configurations can be specified by an untrusted party, attackers may use these ConfigProviders to read arbitrary contents of the disk and environment variables. In particular, this flaw may be used in Apache Kafka Connect to escalate from REST API access to filesystem/environment access, which may be undesirable in certain environments, including SaaS products. This issue affects Apache Kafka Clients: from 2.3.0 through 3.5.2, 3.6.2, 3.7.0. Users with affected applications are recommended to upgrade kafka-clients to version >=3.8.0, and set the JVM system property "org.apache.kafka.automatic.config.providers=none". Users of Kafka Connect with one of the listed ConfigProvider implementations specified in their worker config are also recommended to add appropriate "allowlist.pattern" and "allowed.paths" to restrict their operation to appropriate bounds. For users of Kafka Clients or Kafka Connect in environments that trust users with disk and environment variable access, it is not recommended to set the system property. For users of the Kafka Broker, Kafka MirrorMaker 2.0, Kafka Streams, and Kafka command-line tools, it is not recommended to set the system property. • https://lists.apache.org/thread/9whdzfr0zwdhr364604w5ssnzmg4v2lv • CWE-269: Improper Privilege Management CWE-552: Files or Directories Accessible to External Parties •
CVSS: 7.4EPSS: 0%CPEs: 2EXPL: 0CVE-2024-27309 – Apache Kafka: Potential incorrect access control during migration from ZK mode to KRaft mode
https://notcve.org/view.php?id=CVE-2024-27309
While an Apache Kafka cluster is being migrated from ZooKeeper mode to KRaft mode, in some cases ACLs will not be correctly enforced. Two preconditions are needed to trigger the bug: 1. The administrator decides to remove an ACL 2. The resource associated with the removed ACL continues to have two or more other ACLs associated with it after the removal. When those two preconditions are met, Kafka will treat the resource as if it had only one ACL associated with it after the removal, rather than the two or more that would be correct. The incorrect condition is cleared by removing all brokers in ZK mode, or by adding a new ACL to the affected resource. Once the migration is completed, there is no metadata loss (the ACLs all remain). The full impact depends on the ACLs in use. If only ALLOW ACLs were configured during the migration, the impact would be limited to availability impact. if DENY ACLs were configured, the impact could include confidentiality and integrity impact depending on the ACLs configured, as the DENY ACLs might be ignored due to this vulnerability during the migration period. • http://www.openwall.com/lists/oss-security/2024/04/12/3 https://lists.apache.org/thread/6536rmzyg076lzzdw2xdktvnz163mjpy https://security.netapp.com/advisory/ntap-20240705-0002 • CWE-863: Incorrect Authorization •
