{"id":"CVE-2026-34029","state":"PUBLISHED","title":"Hard-coded cryptographic key in Wertheim SafeController Software allows decryption of sensitive configuration data","description":"The Wertheim SafeController Software, AssemblyVersion 6.15.8328.28014, contains a hard-coded cryptographic key in the SafeSystem.Infrastructure.Security.dll component. An attacker with access to the application files can reverse engineer the DLL and recover the hard-coded cryptographic key. This key can be used to decrypt the licence.whs file, which contains sensitive information about the licensing party and a second key that can be used to decrypt other configuration files.","publishedAt":"2026-06-15T10:05:13.770Z","updatedAt":"2026-06-15T12:27:12.431Z","severity":{"score":6.8,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","source":"SEC-VLab"},"assigner":"SEC-VLab","products":["Wertheim GmbH Wertheim SafeController Software for VAULT ROOMS (Safe Deposit Locker System)"],"affected":[{"vendor":"Wertheim GmbH","product":"Wertheim SafeController Software for VAULT ROOMS (Safe Deposit Locker System)","defaultStatus":"unknown","versions":[{"version":"Wertheim SafeController Software, AssemblyVersion 6.15.8328.28014","status":"affected"}]}],"references":["https://wertheim-safes.com/safe-deposit-box-management/","https://r.sec-consult.com/wertheim"],"weaknesses":["CWE-321"],"ingestedAt":"2026-10-29T20:11:40.391Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/34xxx/CVE-2026-34029.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-34029","state":"PUBLISHED","datePublished":"2026-06-15T10:05:13.770Z","dateUpdated":"2026-06-15T12:27:12.431Z","assignerShortName":"SEC-VLab","assignerOrgId":"551230f0-3615-47bd-b7cc-93e92e730bbf","dateReserved":"2026-03-25T10:46:45.516Z"},"containers":{"cna":{"title":"Hard-coded cryptographic key in Wertheim SafeController Software allows decryption of sensitive configuration data","descriptions":[{"lang":"en","value":"The Wertheim SafeController Software, AssemblyVersion 6.15.8328.28014, contains a hard-coded cryptographic key in the SafeSystem.Infrastructure.Security.dll component.
