"According to its self-reported version number, the version of JetBrains TeamCity running on the
remote host is a version prior to 2023.05.4. It is, therefore, affected by
multiple vulnerabilities:
    
  - In JetBrains TeamCity before 2023.05.4 authentication bypass leading to RCE 
    on TeamCity Server was possible. (CVE-2023-42793)

  - In JetBrains TeamCity before 2023.05.4 stored XSS was possible during nodes configuration
    (CVE-2023-43566)

Note that Nessus did not actually test for these issues, but instead
has relied on the version found in the server's banner.");
