{"id":"CVE-2025-59093","state":"PUBLISHED","title":"Insecure Password Derivation Function for Database Administrator in dormakaba Kaba exos 9300","description":"Exos 9300 instances are using a randomly generated database password to connect to the configured MSSQL server. The password is derived from static random values, which are concatenated to the hostname and a random string that can be read by every user from the registry. This allows an attacker to derive the database password and get authenticated access to the central exos 9300 database as the user Exos9300Common. The user has the roles ExosDialog and ExosDialogDotNet assigned, which are able to read most tables of the database as well as update and insert into many tables.","publishedAt":"2026-01-26T10:03:54.991Z","updatedAt":"2026-01-26T17:24:52.738Z","severity":{"score":8.5,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","source":"SEC-VLab"},"assigner":"SEC-VLab","products":["dormakaba Kaba exos 9300"],"affected":[{"vendor":"dormakaba","product":"Kaba exos 9300","defaultStatus":"affected","versions":[{"version":"All versions, manual mitigation needed!","status":"affected"}]}],"references":["https://r.sec-consult.com/dormakaba","https://r.sec-consult.com/dkexos","https://www.dormakabagroup.com/en/security-advisories"],"weaknesses":["CWE-656"],"ingestedAt":"2026-10-29T20:09:39.787Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/59xxx/CVE-2025-59093.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-59093","state":"PUBLISHED","datePublished":"2026-01-26T10:03:54.991Z","dateUpdated":"2026-01-26T17:24:52.738Z","assignerShortName":"SEC-VLab","assignerOrgId":"551230f0-3615-47bd-b7cc-93e92e730bbf","dateReserved":"2025-09-09T07:52:56.382Z"},"containers":{"cna":{"title":"Insecure Password Derivation Function for Database Administrator in dormakaba Kaba exos 9300","descriptions":[{"lang":"en","value":"Exos 9300 instances are using a randomly generated database password to connect to the configured MSSQL server.
