        "text": "De eerste kwetsbaarheid betreft een onjuiste inputvalidatie van specifieke HTTP-verzoeken in Cisco Nexus Dashboard en Nexus Dashboard Insights. Hierdoor kunnen niet-geauthenticeerde externe aanvallers server-side request forgery (SSRF) aanvallen uitvoeren, wat leidt tot het maken van willekeurige netwerkverzoeken vanaf de getroffen server en mogelijk de uitvoering van kwaadaardige scripts. De tweede kwetsbaarheid zit in de configuratie-backupfunctie van Cisco Nexus Dashboard. Aanvallers die beschikken over zowel het encryptiewachtwoord als de backupbestanden kunnen gevoelige authenticatiedetails ontsleutelen en willekeurige root-commando\u0027s uitvoeren op het apparaat, wat kan resulteren in volledige systeemcompromittering. De derde kwetsbaarheid betreft Cisco Nexus Dashboard Insights, waarbij een geauthenticeerde aanvaller met administratieve rechten via de Metadata update-functie willekeurige bestanden kan schrijven door onvoldoende validatie van handmatig ge\u00fcploade metadata-updatebestanden. Dit kan leiden tot compromittering van de systeemintegriteit.",

An attacker with a valid backup file and encryption password from an affected device could decrypt the backup file. The attacker could then use the authentication details in the backup file to access internal-only APIs on the affected device. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system as the root user."
