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."}],"source":{"advisory":"GHSA-w3jx-4x93-76ph","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T16:01:54.352Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/tgstation/tgstation-server/security/advisories/GHSA-w3jx-4x93-76ph","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/tgstation/tgstation-server/security/advisories/GHSA-w3jx-4x93-76ph"},{"name":"https://github.com/tgstation/tgstation-server/pull/1526","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/tgstation/tgstation-server/pull/1526"}]},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2025-01-06T19:27:12.277382Z","id":"CVE-2023-34243","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2025-01-06T19:27:20.871Z"}}]}}
