Dit kan leiden tot ongeautoriseerde toegang tot gevoelige opgeslagen credentials en geïndexeerde data. De tweede kwetsbaarheid is een path traversal probleem waarbij gebruikers met bepaalde rollen apps kunnen installeren die bestanden buiten de bedoelde app-directory kunnen schrijven, specifiek in de $SPLUNK_HOME/etc/ directory en subdirectories. Dit kan resulteren in ongeautoriseerde wijziging van configuratiebestanden of andere gevoelige data. De derde kwetsbaarheid maakt het mogelijk voor gebruikers zonder 'admin' of 'power' rol om via het /servicesNS/-/-/storage/passwords REST endpoint en de |rest SPL-command toegang te krijgen tot opgeslagen credential hashes, doordat het veld encr_password wordt teruggegeven. Deze kwetsbaarheden beïnvloeden de integriteit en vertrouwelijkheid van data binnen de getroffen Splunk-producten.", "title": "Interpretaties" }, { "category": "description", "text": "Splunk heeft updates uitgebracht om deze kwetsbaarheden te verhelpen.
