Summary Apache Kafka Client is used by IBM App Connect Enterprise Certified Container when running flows that connect to a Kafka server. IBM App Connect Enterprise Certified Container IntegrationServer and IntegrationRuntime operands that use Kafka Client are vulnerable to loss of confidentiality. This bulletin provides patch information to address the reported vulnerability in Apache Kafka Client. [CVE-2024-27817] [CVE-2024-27818] Vulnerability Details CVEID:CVE-2025-27817 DESCRIPTION: A possible arbitrary file read and SSRF vulnerability has been identified in Apache Kafka Client. Apache Kafka Clients accept configuration data for setting the SASL/OAUTHBEARER connection with the brokers, including "sasl.oauthbearer.token.endpoint.url" and "sasl.oauthbearer.jwks.endpoint.url". Apache Kafka allows clients to read an arbitrary file and return the content in the error log, or sending requests to an unintended location. In applications where Apache Kafka Clients configurations can be specified by an untrusted party, attackers may use the "sasl.oauthbearer.token.endpoint.url" and "sasl.oauthbearer.jwks.endpoint.url" configuratin to read arbitrary contents of the disk and environment variables or make requests to an unintended location. In particular, this flaw may be used in Apache Kafka Connect to escalate from REST API access to filesystem/environment/URL access, which may be undesirable in certain environments, including SaaS products. Since Apache Kafka 3.9.1/4.0.0, we have…Read More
