CVE-2021-38153— Apache Kafka 安全漏洞

Timing Attack Vulnerability for Apache Kafka Connect and Clients

Some components in Apache Kafka use `Arrays.equals` to validate a password or key, which is vulnerable to timing attacks that make brute force attacks for such credentials more likely to be successful. Users should upgrade to 2.8.1 or higher, or 3.0.0 or higher where this vulnerability has been fixed. The affected versions include Apache Kafka 2.0.0, 2.0.1, 2.1.0, 2.1.1, 2.2.0, 2.2.1, 2.2.2, 2.3.0, 2.3.1, 2.4.0, 2.4.1, 2.5.0, 2.5.1, 2.6.0, 2.6.1, 2.6.2, 2.7.0, 2.7.1, and 2.8.0.

Apache Kafka 安全漏洞

Apache Kafka是美国阿帕奇（Apache）基金会的一套开源的分布式流媒体平台。该平台能够获取实时数据，用于构建对数据流的变化进行实时反应的应用程序。 Apache Kafka 存在安全漏洞，该漏洞源于 Apache Kafka 中的某些组件使用Arrays.equals来验证密码或密钥，容易受到定时攻击。本地用户可以滥用Arrays.equals来暴力破解访问凭据并提升系统权限。
