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

  - Jenkins 2.275 and LTS 2.263.2 allows reading arbitrary files using the file browser for workspaces and
    archived artifacts due to a time-of-check to time-of-use (TOCTOU) race condition. (CVE-2021-21615)

The version of Jenkins Enterprise or Jenkins Operations Center running on the remote web server is 2.222.x prior to 2.222.43.0.2, 2.249.x prior to 2.249.30.0.2, or 2.x prior to 2.263.2.3. It is, therefore, affected by an arbitrary file read vulnerability due to a time-of-check to time-of-use (TOCTOU) race condition. An authenticated, remote attacker can exploit this, via the workspace browser, to access files outside workspaces.

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

The version of Jenkins running on the remote web server is prior to 2.276 weekly or 2.263.3 LTS. It is, therefore, affected by a time-of-check to time-of-use (TOCTOU) race condition that allows reading arbitrary files using the file browser for workspaces and archived artifacts.

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