Summary
Kwetsbaarheden verholpen in Cisco Nexus Dashboard en Nexus Dashboard Insights
Notes
The Netherlands Cyber Security Center (henceforth: NCSC-NL) maintains this page to enhance access to its information and security advisories. The use of this security advisory is subject to the following terms and conditions: NCSC-NL makes every reasonable effort to ensure that the content of this page is kept up to date, and that it is accurate and complete. Nevertheless, NCSC-NL cannot entirely rule out the possibility of errors, and therefore cannot give any warranty in respect of its completeness, accuracy or continuous keeping up-to-date. The information contained in this security advisory is intended solely for the purpose of providing general information to professional users. No rights can be derived from the information provided therein. NCSC-NL and the Kingdom of the Netherlands assume no legal liability or responsibility for any damage resulting from either the use or inability of use of this security advisory. This includes damage resulting from the inaccuracy of incompleteness of the information contained in the advisory. This security advisory is subject to Dutch law. All disputes related to or arising from the use of this advisory will be submitted to the competent court in The Hague. This choice of means also applies to the court in summary proceedings.
Feiten: Cisco heeft kwetsbaarheden verholpen in Cisco Nexus Dashboard en Cisco Nexus Dashboard Insights.
Interpretaties: 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's 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 geüploade metadata-updatebestanden. Dit kan leiden tot compromittering van de systeemintegriteit.
Oplossingen: Cisco heeft updates uitgebracht om deze kwetsbaarheden in Nexus Dashboard en Nexus Dashboard Insights te verhelpen. Zie bijgevoegde referenties voor meer informatie.
Kans: medium
Schade: high
CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
CWE-295: Improper Certificate Validation
CWE-918: Server-Side Request Forgery (SSRF)
CVE-2026-20041

A vulnerability in Cisco Nexus Dashboard and Cisco Nexus Dashboard Insights allows unauthenticated remote attackers to perform server-side request forgery (SSRF) via improper input validation, enabling arbitrary network requests and script execution.

6.1 (Medium)
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
CWE-918 - Server-Side Request Forgery (SSRF)
CVE-2026-20042

A vulnerability in Cisco Nexus Dashboard's configuration backup feature allows attackers with encryption credentials and backup files to decrypt sensitive authentication data and potentially execute arbitrary root commands.

6.5 (Medium)
CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:N
CWE-295 - Improper Certificate Validation
CVE-2026-20174

A vulnerability in Cisco Nexus Dashboard Insights' Metadata update feature allows an authenticated attacker with administrative credentials to write arbitrary files due to insufficient validation of metadata update files.

4.9 (Medium)
CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:N
CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
