{"id":"CVE-2023-34243","state":"PUBLISHED","title":"Windows user name disclosure in TGstation","description":"TGstation is a toolset to manage production BYOND servers. In affected versions if a Windows user was registered in tgstation-server (TGS), an attacker could discover their username by brute-forcing the login endpoint with an invalid password. When a valid Windows logon was found, a distinct response would be generated. This issue has been addressed in version 5.12.5. Users are advised to upgrade. Users unable to upgrade may be mitigated by rate-limiting API calls with software that sits in front of TGS in the HTTP pipeline such as fail2ban.","publishedAt":"2023-06-08T21:09:14.628Z","updatedAt":"2025-01-06T19:27:20.871Z","severity":{"score":5.8,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["tgstation tgstation-server"],"affected":[{"vendor":"tgstation","product":"tgstation-server","versions":[{"version":">= 4.0.0, < 5.12.5","status":"affected"}]}],"references":["https://github.com/tgstation/tgstation-server/security/advisories/GHSA-w3jx-4x93-76ph","https://github.com/tgstation/tgstation-server/pull/1526"],"weaknesses":["CWE-200"],"ingestedAt":"2026-10-29T20:06:00.499Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2023/34xxx/CVE-2023-34243.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2023-34243","state":"PUBLISHED","datePublished":"2023-06-08T21:09:14.628Z","dateUpdated":"2025-01-06T19:27:20.871Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2023-05-31T13:51:51.172Z"},"containers":{"cna":{"title":"Windows user name disclosure in TGstation","descriptions":[{"lang":"en","value":"TGstation is a toolset to manage production BYOND servers.
