Apache Hadoop Vulnerability Analysis: CVE-2023-26031 Privilege Escalation and CVE-2023-26253 RCE

From the provided image, we can summarize key information about Hadoop vulnerabilities, particularly focusing on the two highest CVSS-rated vulnerabilities: CVE-2023-26031 and CVE-2023-26253. ### CVE-2023-26031: Privilege Escalation - **Description**: This vulnerability arises from a flaw in the Linux Container Executor binary in Apache Hadoop. A local attacker can exploit this flaw to gain root privileges. - **Impact**: Privilege escalation on systems running the affected versions. - **Affected Versions**: Hadoop versions from 2.3.0 to 2.7.7 and from 2.8.0 to 2.9.2 are affected. - **Recommendations**: Upgrade to Hadoop 3.3.5 or later versions, which do not include JMSAppender in the Log4j configuration. ### CVE-2023-26253: Remote Code Execution - **Description**: This vulnerability stems from a flaw in how Hadoop YARN deserializes data retrieved from ZooKeeper. An attacker with access to ZooKeeper can execute arbitrary commands as the YARN user by exploiting this vulnerability. - **Impact**: Remote code execution on the YARN master node. - **Affected Versions**: Hadoop versions from 2.8.0 to 2.9.1, and from 3.0.0-alpha1 to 3.0.0, 3.0.1, 3.1.0, and 3.2.0 are affected. - **Recommendations**: Upgrade to a fixed version that safely serializes and deserializes data. The provided markdown text outlines critical vulnerabilities and their impact on systems running Apache Hadoop. It also includes mitigation recommendations and lists the affected Hadoop versions. For CVE-2023-26031, upgrading to a fixed version (Hadoop 3.3.5 or later) is recommended. For CVE-2023-26253, the recommendation is to upgrade to a version that safely handles serialization/deserialization of data.
