The vulnerability is due to improper input validation in the XML API service. An attacker could exploit this vulnerability by sending a malformed XML packet. A successful exploit could cause the XML API service to stop responding. Cisco has confirmed the vulnerability in a security notice and released software updates. To exploit this vulnerability, an attacker must be able to send malformed XML packets to the targeted device, which may reside on trusted, internal networks to which the attacker would likely need access. This access requirement may reduce the likelihood 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":"2013-09-27T02:14:02Z","updated_at":"2013-09-27T02:14:02Z","source_url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/Cisco-SA-20130927-CVE-2012-4079","csaf_url":"https://sec.cloudapps.cisco.com/security/center/contentjson/CiscoSecurityAdvisory/Cisco-SA-20130927-CVE-2012-4079/csaf/Cisco-SA-20130927-CVE-2012-4079.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":0.01218},"cves":[{"id":"CVE-2012-4079","kev":false,"epss":{"score":0.01218,"percentile":0.65279,"score_date":"2026-07-20","updated_at":"2026-07-21T05:16:32Z"}}],"public_evidence":[{"product":{"name":"Cisco Unified Computing System (Managed)","slug":"cisco-unified-computing-system-managed","vendor":"Cisco"},"cve":{"id":"CVE-2012-4079"},"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":"2026-07-20T05:15:17Z","csaf_status":"known_affected","csaf_product_status":"known_affected","csaf_product_status_path":"vulnerabilities[].product_status.known_affected","raw_product_name":"Cisco Unified Computing System (Managed)","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":0.01218,"score_date":"2026-07-20","updated_at":"2026-07-21T05:16:32Z"},"published_at":"2013-09-27T02:14:02Z","updated_at":"2013-09-27T02:14:02Z","advisory_updated_at":"2013-09-27T02:14:02Z","source_url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/Cisco-SA-20130927-CVE-2012-4079","row_display_order":1}]}
