Jenkins 2.217 through 2.441 (both inclusive), LTS 2.222.1 through 2.426.2 (both inclusive) does not perform origin validation of requests made through the CLI WebSocket endpoint, resulting in a cross-site WebSocket hijacking (CSWSH) vulnerability, allowing attackers to execute CLI commands on the Jenkins controller.

A vulnerability exists in Jenkins versions from 2.217 before 2.442 and from LTS 2.222.1 before LTS 2.426.3 allowing an unauthenticated and remote attacker to trick a user authenticated on the target Jenkins instance and perform Jenkins CLI cross-site arbitrary commands through websockets.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Jenkins 2.217 through 2.441 (both inclusive), LTS 2.222.1 through 2.426.2 (both inclusive) does not
    perform origin validation of requests made through the CLI WebSocket endpoint, resulting in a cross-site
    WebSocket hijacking (CSWSH) vulnerability, allowing attackers to execute CLI commands on the Jenkins
    controller. (CVE-2024-23898)

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:0775 advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 8b03d274-56ca-489e-821a-cf32f07643f0 advisory.

  - Jenkins 2.441 and earlier, LTS 2.426.2 and earlier does not disable a feature of its CLI command parser     that replaces an '@' character followed by a file path in an argument with the file's contents, allowing     unauthenticated attackers to read arbitrary files on the Jenkins controller file system. (CVE-2024-23897)

  - Jenkins 2.217 through 2.441 (both inclusive), LTS 2.222.1 through 2.426.2 (both inclusive) does not     perform origin validation of requests made through the CLI WebSocket endpoint, resulting in a cross-site     WebSocket hijacking (CSWSH) vulnerability, allowing attackers to execute CLI commands on the Jenkins     controller. (CVE-2024-23898)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

According to its its self-reported version number, the version of Jenkins running on the remote web server is Jenkins LTS prior to 2.426.3 or Jenkins weekly prior to 2.442. It is, therefore, affected by multiple vulnerabilities:
