"According to its its self-reported version number, the version of JetBrains TeamCity running on the
remote host is a version prior to 2023.05. It is, therefore, affected by
multiple vulnerabilities:
    
  - In JetBrains TeamCity before 2023.05 bypass of permission checks allowing to perform admin actions was possible
    (CVE-2023-34218)

  - In JetBrains TeamCity before 2023.05 improper permission checks allowed users without appropriate permissions to 
    edit Build Configuration settings via REST API (CVE-2023-34219)

  - In JetBrains TeamCity before 2023.05 stored XSS in the Commit Status Publisher window was possible
    (CVE-2023-34220)

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