Technitium DNS Server is een open source DNS-server met uitgebreide mogelijkheden, die kan worden gebruikt om ad- en malware buiten de deur te houden en je privacy te beschermen. Het is daarmee tot op zekere hoogte vergelijkbaar met Pi-hole en AdGuard Home. De software is beschikbaar voor Windows, Linux, macOS en Docker en is eenvoudig op te zetten en eenvoudig in gebruik. Versie 15.6 is uitgekomen en hier zijn de volgende verbeteringen in aangebracht:
Version 15.6
- Added a new explicit option in Settings to enable/disable Cache Prefetch feature.
- Fixed recursive resolution issues when using Prefer IPv6 mode that caused resolution failures due to hitting Max Outbound Requests limit.
- Fixed bug in DNS Cache that caused a failure record entry to shadow CNAME record in cache causing cache misses and resolution errors in certain scenarios.
- Fixed session token prefix oracle vulnerability reported by Elias Hasas from Brickell Technologies LLC. This allowed an authenticated user to recover full session token for all active sessions on the DNS server using delete sessions API.
- Fixed DoS issue with change password iterations count reported by Robert Cronin. This allowed an authenticated user to set arbitrary iterations value to cause high CPU usage on the server.
- Fixed DoS issue with zone name filtering feature reported by Robert Cronin. This allowed an authenticated user to abuse the filter to inject regex pattern that could cause high CPU usage on the server.
- Fixed log injection vulnerability in login API call reported by Phillip Hernandez, independent researcher. This allowed an unauthenticated attacker to inject text in log file by abusing username parameter in the login API call.
- Multiple other minor bug fixes and improvements.
