"The version of JetBrains TeamCity installed on the remote host is prior to 2018.2.2. It is, therefore, affected by
multiple vulnerabilities:

  - Incorrect handling of user input in ZIP extraction was detected in JetBrains TeamCity. The issue was fixed
    in TeamCity 2018.2.2. (CVE-2019-12841)

  - A reflected XSS on a user page was detected on one of the JetBrains TeamCity pages. The issue was fixed in
    TeamCity 2018.2.2. (CVE-2019-12842)

  - A user without the required permissions could gain access to some JetBrains TeamCity settings. The issue
    was fixed in TeamCity 2018.2.2. (CVE-2019-12846)

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