The version of Jenkins Enterprise or Jenkins Operations Center running on the remote web server is 2.222.x prior to 2.222.43.0.1, 2.249.x prior to 2.249.30.0.1, or 2.x prior to 2.263.2.2. It is, therefore, affected by multiple vulnerabilities, including the following:

  - Jenkins 2.274 and earlier, LTS 2.263.1 and earlier allows attackers with permission to create or configure     various objects to inject crafted content into Old Data Monitor that results in the instantiation of     potentially unsafe objects once discarded by an administrator. (CVE-2021-21604)

  - Jenkins 2.274 and earlier, LTS 2.263.1 and earlier allows users with Agent/Configure permission to choose     agent names that cause Jenkins to override the global `config.xml` file. (CVE-2021-21605)

  - Jenkins 2.274 and earlier, LTS 2.263.1 and earlier does not correctly match requested URLs to the list of     always accessible paths, allowing attackers without Overall/Read permission to access some URLs as if they     did have Overall/Read permission. (CVE-2021-21609)

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