An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2016-6407 in the wild and no public exploit code.\n\nAffected product: Cisco Web Security Appliance. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2016-6407/ (Markdown: https://insights.sbomify.com/CVE-2016-6407/index.md)","id":"CVE-2016-6407","markdown":"https://insights.sbomify.com/CVE-2016-6407/index.md","name":"CVE-2016-6407","record":{"aliases":["GHSA-83cp-8php-jfpv"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Web Security Appliance","requires_auth":"none","summary":"Remote attackers can cause denial of service on Cisco Web Security Appliances by sending simultaneous HTTP requests with overlapping byte ranges.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"web_security_appliance","vendor":"cisco"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-399","name":null}],"description":"Cisco AsyncOS through 9.5.0-444 on Web Security Appliance (WSA) devices allows remote attackers to cause a denial of service (link saturation) by making many HTTP requests for overlapping byte ranges simultaneously, aka Bug ID CSCuz27219.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Denial of service in n/a","id":"CVE-2016-6407","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:web_security_appliance","products":["cisco:web_security_appliance"],"type":"denial_of_service","year":"2016"},"n_packages":0,"n_references":3,"next":{"headline":"XML external entity in n/a","id":"CVE-2016-6408"},"packages":[],"prev":{"headline":"Auth bypass in n/a","id":"CVE-2016-6406"},"products":["n/a"],"published":"2016-09-17","related":[{"cvss_score":9,"headline":"Command injection in n/a","id":"CVE-2015-6298","kev_date_added":null,"published":"2015-11-06"},{"cvss_score":8.6,"headline":"Cisco Web Security Appliance Malformed Request Denial of Service Vulnerability","id":"CVE-2019-1817","kev_date_added":null,"published":"2019-05-03"},{"cvss_score":8.6,"headline":"Denial of service in AsyncOS Software for Cisco Web Security Appliances","id":"CVE-2018-0410","kev_date_added":null,"published":"2018-08-15"},{"cvss_score":7.8,"headline":"Denial of service in n/a","id":"CVE-2015-6292","kev_date_added":null,"published":"2015-11-06"},{"cvss_score":7.8,"headline":"Denial of service in n/a","id":"CVE-2015-6293","kev_date_added":null,"published":"2015-11-06"},{"cvss_score":7.5,"headline":"Security feature bypass in Cisco Web Security Appliance unknown","id":"CVE-2018-0353","kev_date_added":null,"published":"2018-06-07"},{"cvss_score":7.5,"headline":"Hardcoded credentials in Cisco Web Security Appliance","id":"CVE-2017-6750","kev_date_added":null,"published":"2017-07-25"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can cause denial of service on Cisco Web Security Appliances by sending simultaneous HTTP requests with overlapping byte ranges.","url":"https://insights.sbomify.com/CVE-2016-6407/"}
