An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2024-27198 in the wild since at least 7 Mar 2024, including in ransomware campaigns.\n\nAffected product: Jetbrains Teamcity. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2024-27198/ (Markdown: https://insights.sbomify.com/CVE-2024-27198/index.md)","id":"CVE-2024-27198","markdown":"https://insights.sbomify.com/CVE-2024-27198/index.md","name":"CVE-2024-27198","record":{"aliases":["GHSA-xh94-49wq-7h2h"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"CI/CD server","requires_auth":"none","summary":"Attackers can bypass authentication to perform admin actions in JetBrains TeamCity, requiring an upgrade to secure the CI/CD pipeline.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"JetBrains","cpe":[{"product":"teamcity","vendor":"jetbrains"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-288","name":"Authentication Bypass Using an Alternate Path or Channel"}],"description":"In JetBrains TeamCity before 2023.11.4 authentication bypass allowing to perform admin actions was possible","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2024-03-04","github_poc":20,"max_poc_stars":153,"metasploit":1,"nuclei":1,"refs":[{"date":"2024-03-06T03:15:03Z","kind":"github_poc","ref":"https://github.com/W01fh4cker/CVE-2024-27198-RCE","stars":153,"title":"CVE-2024-27198 \u0026 CVE-2024-27199 Authentication Bypass --\u003e RCE in JetBrains TeamCity Pre-2023.11.4"},{"date":"2024-03-05T05:43:06Z","kind":"github_poc","ref":"https://github.com/yoryio/CVE-2024-27198","stars":37,"title":"Exploit for CVE-2024-27198 -
