The vulnerability is due to insufficient validation of user-supplied values. An attacker could exploit this vulnerability by sending multiple request parameters to an affected device. Cisco has confirmed the vulnerability and released software updates. A successful exploit of this vulnerability could allow an attacker to bypass authentication and gain unauthorized access to the targeted device. If successful, the attacker could have the ability to conduct further attacks, which may impact the confidentiality, integrity, or availability of the device. 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":"2015-07-14T12:42:06Z","updated_at":"2015-07-14T12:42:06Z","source_url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/Cisco-SA-20150714-CVE-2015-4271","csaf_url":"https://sec.cloudapps.cisco.com/security/center/contentjson/CiscoSecurityAdvisory/Cisco-SA-20150714-CVE-2015-4271/csaf/Cisco-SA-20150714-CVE-2015-4271.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":0.0236},"cves":[{"id":"CVE-2015-4271","kev":false,"epss":{"score":0.0236,"percentile":0.8188,"score_date":"2026-07-19","updated_at":"2026-07-20T05:46:47Z"}}],"public_evidence":[{"product":{"name":"Cisco TelePresence TC Software","slug":"cisco-telepresence-tc-software","vendor":"Cisco"},"cve":{"id":"CVE-2015-4271"},"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":"2026-07-20T04:58:12Z","csaf_status":"known_affected","csaf_product_status":"known_affected","csaf_product_status_path":"vulnerabilities[].product_status.known_affected","raw_product_name":"Cisco TelePresence TC 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":0.0236,"score_date":"2026-07-19","updated_at":"2026-07-20T05:46:47Z"},"published_at":"2015-07-14T12:42:06Z","updated_at":"2015-07-14T12:42:06Z","advisory_updated_at":"2015-07-14T12:42:06Z","source_url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/Cisco-SA-20150714-CVE-2015-4271","row_display_order":1}]}
