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."}],"references":[{"url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-nd-cbid-5YqkOSHu","name":"cisco-sa-nd-cbid-5YqkOSHu"}],"exploits":[{"lang":"en","value":"The Cisco PSIRT is not aware of any public announcements or malicious use of the vulnerability that is described in this advisory."}],"source":{"advisory":"cisco-sa-nd-cbid-5YqkOSHu","discovery":"INTERNAL","defects":["CSCwq66302"]},"problemTypes":[{"descriptions":[{"lang":"en","description":"Improper Certificate Validation","type":"cwe","cweId":"CWE-295"}]}],"affected":[{"vendor":"Cisco","product":"Cisco Nexus Dashboard","versions":[{"version":"1.1(3e)","status":"affected"},{"version":"1.1(3c)","status":"affected"},{"version":"1.1(3d)","status":"affected"},{"version":"1.1(0d)","status":"affected"},{"version":"1.1(2i)","status":"affected"},{"version":"2.0(1b)","status":"affected"},{"version":"1.1(2h)","status":"affected"},{"version":"1.1(0c)","status":"affected"},{"version":"1.1(3f)","status":"affected"},{"version":"2.1(1d)","status":"affected"},{"version":"2.1(1e)","status":"affected"},{"version":"2.0(2g)","status":"affected"},{"version":"2.0(2h)","status":"affected"},{"version":"2.1(2d)","status":"affected"},{"version":"2.0(1d)","status":"affected"},{"version":"2.2(1h)","status":"affected"},{"version":"2.2(1e)","status":"affected"},{"version":"2.2(2d)","status":"affected"},{"version":"2.1(2f)","status":"affected"},{"version":"2.3(1c)","status":"affected"},{"version":"2.3(2b)","status":"affected"},{"version":"2.3(2c)","status":"affected"},{"version":"2.3(2d)","status":"affected"},{"version":"2.3(2e)","status":"affected"},{"version":"3.0(1f)","status":"affected"},{"version":"3.0(1i)","status":"affected"},{"version":"3.1(1k)","status":"affected"},{"version":"3.1(1l)","status":"affected"},{"version":"3.2(1e)","status":"affected"},{"version":"3.2(1i)","status":"affected"},{"version":"3.3(1a)","status":"affected"},{"version":"3.3(1b)","status":"affected"},{"version":"3.3(2b)","status":"affected"},{"version":"4.0(1i)","status":"affected"},{"version":"3.3(2g)","status":"affected"},{"version":"3.2(2f)","status":"affected"},{"version":"3.2(2g)","status":"affected"},{"version":"3.2(2m)","status":"affected"},{"version":"3.1(1n)","status":"affected"},{"version":"4.1(1g)","status":"affected"}],"defaultStatus":"unknown"}],"providerMetadata":{"orgId":"d1c1063e-7a18-46af-9102-31f8928bc633","shortName":"cisco","dateUpdated":"2026-04-01T16:27:49.948Z"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-04-01T00:00:00+00:00","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3","id":"CVE-2026-20042"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-04-02T03:56:08.575Z"}}]}}
