CVE-2024-2216: 
Java vulnerability analysis and mitigation

A missing permission check vulnerability (CVE-2024-2216) affects the Jenkins docker-build-step Plugin versions 2.11 and earlier. The vulnerability was discovered and reported by Andrea Chiera from CloudBees, Inc., and was publicly disclosed on March 6, 2024 (Jenkins Advisory).

The vulnerability stems from a missing permission check in an HTTP endpoint that implements a connection test functionality. The issue allows attackers who have Overall/Read permission to connect to an attacker-specified TCP or Unix socket URL. The vulnerability has been assigned a severity rating of Medium (Jenkins Advisory, OSS Security).

The vulnerability enables attackers to reconfigure the plugin using provided connection test parameters, which affects future build step executions. This means that an attacker with basic read permissions can potentially manipulate the plugin's configuration and impact subsequent build operations (Jenkins Advisory).

The vulnerability can be exploited by attackers who possess Overall/Read permission in the Jenkins environment. The attack vector involves accessing an HTTP endpoint that lacks proper permission checks, allowing unauthorized connection attempts to specified TCP or Unix socket URLs (Jenkins Advisory).

As of the advisory publication on March 6, 2024, there is no fix available for this vulnerability in the docker-build-step Plugin. Organizations using affected versions (2.11 and earlier) should monitor for updates and consider implementing additional access controls to restrict Overall/Read permissions (Jenkins Advisory).
