The attacker must authenticate with valid administrator device credentials. The vulnerability is due to the incorrect implementation of a CLI command that allows a Bash command to be incorrectly invoked on the Guest Shell CLI. An attacker could exploit this vulnerability by authenticating to the device and entering a crafted command at the Guest Shell prompt. A successful exploit could allow the attacker to issue commands that should be restricted by a Guest Shell account.","severity":"MEDIUM","kev":false,"epss":{"score":0.00049,"percentile":0.15084,"score_date":"2026-05-19","updated_at":"2026-05-20T02:10:44Z"},"cvss_score":6.7,"cvss_source":"NVD","cwe":"CWE-264","published_at":"2019-05-15T17:29:01Z","modified_at":"2024-11-21T04:37:11Z"},"freshness":{"last_source_refreshed_at":"2026-05-26T00:00:03Z","latest_source_refresh_at":"2026-05-26T00:00:03Z","oldest_source_refresh_at":"2026-05-22T00:16:33Z","all_sources_fresh":false,"sources":[{"source":"cisco_advisories","label":"Cisco advisories","last_success_at":"2026-05-26T00:00:03Z","stale":true},{"source":"cisco_csaf","label":"Cisco CSAF","last_success_at":"2026-05-25T03:03:26Z","stale":true},{"source":"nvd_cves","label":"NVD CVEs","last_success_at":"2026-05-22T00:16:33Z","stale":true},{"source":"cisa_kev","label":"CISA KEV","last_success_at":"2026-05-22T00:16:34Z","stale":true},{"source":"first_epss","label":"EPSS","last_success_at":"2026-05-22T00:16:40Z","stale":true}]},"summary":{"advisory_count":1,"visible_product_count":2,"public_evidence_count":2,"kev":false,"cvss_score":6.7},"advisories":[{"id":"cisco-sa-20190515-nxos-bash-bypass","slug":"cisco-sa-20190515-nxos-bash-bypass","title":"Cisco NX-OS Software Bash Bypass Guest Shell Vulnerability","source_url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190515-nxos-bash-bypass"}],"public_evidence":[{"product":{"name":"Cisco NX-OS Software","slug":"cisco-nx-os-software","vendor":"Cisco"},"advisory":{"id":"cisco-sa-20190515-nxos-bash-bypass","slug":"cisco-sa-20190515-nxos-bash-bypass","title":"Cisco NX-OS Software Bash Bypass Guest Shell Vulnerability","source_url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190515-nxos-bash-bypass"},"evidence_type":"structured_affected","evidence_label":{"scope":"CSAF product evidence","label":"product_status known affected"},"evidence_source":"Cisco CSAF","source":"Cisco CSAF","source_document_fetched_at":"2026-05-19T19:57:55Z","csaf_status":"known_affected","csaf_product_status":"known_affected","csaf_product_status_path":"vulnerabilities[].product_status.known_affected","raw_product_name":"7.0(0)N1(1);
