An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-43566 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-2023-43566/ (Markdown: https://insights.sbomify.com/CVE-2023-43566/index.md)","id":"CVE-2023-43566","markdown":"https://insights.sbomify.com/CVE-2023-43566/index.md","name":"CVE-2023-43566","record":{"aliases":["GHSA-56qf-rm6g-9hvq"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["account_takeover","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"CI/CD server","requires_auth":"high_privilege","summary":"Stored XSS in TeamCity nodes configuration allows attackers to execute scripts in victim browsers, potentially leading to account takeover.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"JetBrains","cpe":[{"product":"teamcity","vendor":"jetbrains"}],"cvss":{"score":3.5,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"In JetBrains TeamCity before 2023.05.4 stored XSS was possible during nodes configuration","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":"Cross-site scripting in TeamCity","id":"CVE-2023-43566","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"jetbrains:teamcity","products":["jetbrains:teamcity"],"type":"xss","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in Desktop BIOS","id":"CVE-2023-43567"},"packages":[],"prev":{"headline":"Buffer Copy Without Checking Size of Input in Hypervisor","id":"CVE-2023-43556"},"products":["TeamCity"],"published":"2023-09-19","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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-09-24","vendors":["JetBrains"]},"summary":"Stored XSS in TeamCity nodes configuration allows attackers to execute scripts in victim browsers, potentially leading to account takeover.","url":"https://insights.sbomify.com/CVE-2023-43566/"}
