An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-37546 in the wild and no public exploit code.\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-2021-37546/ (Markdown: https://insights.sbomify.com/CVE-2021-37546/index.md)","id":"CVE-2021-37546","markdown":"https://insights.sbomify.com/CVE-2021-37546/index.md","name":"CVE-2021-37546","record":{"aliases":["GHSA-2p84-f2f6-w7c4"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"CI/CD server","requires_auth":"none","summary":"Insecure key generation in TeamCity allows attackers to decrypt sensitive properties, exposing confidential data.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"teamcity","vendor":"jetbrains"}],"cvss":{"score":5.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-327","name":"Use of a Broken or Risky Cryptographic Algorithm"}],"description":"In JetBrains TeamCity before 2021.1, an insecure key generation mechanism for encrypted properties was used.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Weak cryptography in n/a","id":"CVE-2021-37546","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"jetbrains:teamcity","products":["jetbrains:teamcity"],"type":"weak_cryptography","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"File upload in n/a","id":"CVE-2021-37547"},"packages":[],"prev":{"headline":"Auth bypass in n/a","id":"CVE-2021-37545"},"products":["n/a"],"published":"2021-08-06","related":[{"cvss_score":9.8,"headline":"JetBrains TeamCity Deserialization of Untrusted Data","id":"CVE-2026-63077","kev_date_added":"2026-08-05","published":"2026-07-27"},{"cvss_score":9.8,"headline":"JetBrains TeamCity Authentication Bypass","id":"CVE-2024-27198","kev_date_added":"2024-03-07","published":"2024-03-04"},{"cvss_score":9.8,"headline":"JetBrains TeamCity Authentication Bypass","id":"CVE-2023-42793","kev_date_added":"2023-10-04","published":"2023-09-19"},{"cvss_score":7.3,"headline":"JetBrains TeamCity Relative Path Traversal","id":"CVE-2024-27199","kev_date_added":"2026-04-20","published":"2024-03-04"},{"cvss_score":9.8,"headline":"Auth bypass in TeamCity","id":"CVE-2024-23917","kev_date_added":null,"published":"2024-02-06"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2022-24331","kev_date_added":null,"published":"2022-02-25"},{"cvss_score":9.8,"headline":"XML external entity in n/a","id":"CVE-2022-24340","kev_date_added":null,"published":"2022-02-25"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Insecure key generation in TeamCity allows attackers to decrypt sensitive properties, exposing confidential data.","url":"https://insights.sbomify.com/CVE-2021-37546/"}
