The vulnerability is caused when the file descriptors are exhausted during a FIN attack. An attacker could exploit this vulnerability by launching a FIN attack at the control card. An exploit could allow the attacker to prevent system write access to the flash memory. Cisco has confirmed the vulnerability in a security notice and released software updates. To exploit this vulnerability, an attacker may need access to trusted, internal networks to attempt to conduct a FIN attack at the control card on a targeted device. This access requirement may reduce the possibility of a successful exploit. Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available.","severity":"Medium","published_at":"2014-04-08T17:34:35Z","updated_at":"2014-04-08T17:34:35Z","source_url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/Cisco-SA-20140408-CVE-2014-2139","csaf_url":"https://sec.cloudapps.cisco.com/security/center/contentjson/CiscoSecurityAdvisory/Cisco-SA-20140408-CVE-2014-2139/csaf/Cisco-SA-20140408-CVE-2014-2139.json","exposure_verdict":"not_assessed","verdict_reason":"Public evidence does not evaluate exact release, platform, enabled features, configuration, compensating controls, or live exposure."},"freshness":{"last_source_refreshed_at":"2026-07-21T05:16:34Z","latest_source_refresh_at":"2026-07-21T05:16:34Z","oldest_source_refresh_at":"2026-07-21T03:00:03Z","all_sources_fresh":true,"sources":[{"source":"cisco_advisories","label":"Cisco advisories","last_success_at":"2026-07-21T03:00:03Z","stale":false},{"source":"cisco_csaf","label":"Cisco CSAF","last_success_at":"2026-07-21T05:14:24Z","stale":false},{"source":"nvd_cves","label":"NVD CVEs","last_success_at":"2026-07-21T05:16:30Z","stale":false},{"source":"cisa_kev","label":"CISA KEV","last_success_at":"2026-07-21T05:16:31Z","stale":false},{"source":"first_epss","label":"EPSS","last_success_at":"2026-07-21T05:16:34Z","stale":false}]},"summary":{"cve_count":1,"visible_product_count":1,"public_evidence_count":1,"kev_count":0,"highest_epss":0.01761},"cves":[{"id":"CVE-2014-2139","kev":false,"epss":{"score":0.01761,"percentile":0.75537,"score_date":"2026-07-20","updated_at":"2026-07-21T05:16:32Z"}}],"public_evidence":[{"product":{"name":"Cisco ONS 15454 System Software","slug":"cisco-ons-15454-system-software","vendor":"Cisco"},"cve":{"id":"CVE-2014-2139"},"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":"2026-07-20T04:29:42Z","csaf_status":"known_affected","csaf_product_status":"known_affected","csaf_product_status_path":"vulnerabilities[].product_status.known_affected","raw_product_name":"Cisco ONS 15454 System Software","exposure_verdict":"not_assessed","verdict_reason":"Public evidence does not evaluate exact release, platform, enabled features, configuration, compensating controls, or live exposure.","exposure_verdict_reason":"Public evidence does not evaluate exact release, platform, enabled features, configuration, compensating controls, or live exposure.","kev":false,"epss":{"score":0.01761,"score_date":"2026-07-20","updated_at":"2026-07-21T05:16:32Z"},"published_at":"2014-04-08T17:34:35Z","updated_at":"2014-04-08T17:34:35Z","advisory_updated_at":"2014-04-08T17:34:35Z","source_url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/Cisco-SA-20140408-CVE-2014-2139","row_display_order":1}]}
