The vulnerability occurs because the affected software does not properly allocate space for the HTTP header and any expected HTTP payload. An attacker could exploit this vulnerability by sending a crafted HTTP request to the affected device. An exploit could allow the attacker to cause a DoS condition when the proxy process unexpectedly reloads, which can cause traffic to be dropped. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.   This advisory is available at the following link:  https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20160518-wsa3","severity":"High","published_at":"2016-05-18T23:00:00Z","updated_at":"2016-05-18T23:00:00Z","source_url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20160518-wsa3","csaf_url":"https://sec.cloudapps.cisco.com/security/center/contentjson/CiscoSecurityAdvisory/cisco-sa-20160518-wsa3/csaf/cisco-sa-20160518-wsa3.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":0.01931},"cves":[{"id":"CVE-2016-1382","kev":false,"epss":{"score":0.01931,"percentile":0.77786,"score_date":"2026-07-20","updated_at":"2026-07-21T05:16:33Z"}}],"public_evidence":[{"product":{"name":"Cisco Web Security Appliance (WSA)","slug":"cisco-web-security-appliance-wsa","vendor":"Cisco"},"cve":{"id":"CVE-2016-1382"},"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":"2026-07-20T04:52:53Z","csaf_status":"known_affected","csaf_product_status":"known_affected","csaf_product_status_path":"vulnerabilities[].product_status.known_affected","raw_product_name":"Cisco Web Security Appliance (WSA)","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":0.01931,"score_date":"2026-07-20","updated_at":"2026-07-21T05:16:33Z"},"published_at":"2016-05-18T23:00:00Z","updated_at":"2016-05-18T23:00:00Z","advisory_updated_at":"2016-05-18T23:00:00Z","source_url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20160518-wsa3","row_display_order":1}]}
