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-2016-6416 in the wild and no public exploit code.\n\nAffected product: Cisco Email 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-2016-6416/ (Markdown: https://insights.sbomify.com/CVE-2016-6416/index.md)","id":"CVE-2016-6416","markdown":"https://insights.sbomify.com/CVE-2016-6416/index.md","name":"CVE-2016-6416","record":{"aliases":["GHSA-7cpm-6ch9-5qff"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Security Appliance","requires_auth":"none","summary":"Remote attackers can cause a denial of service on Cisco Email, Web, and Content Security Appliances by flooding the FTP service with traffic.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"content_security_management_appliance","vendor":"cisco"},{"product":"email_security_appliance","vendor":"cisco"},{"product":"web_security_appliance","vendor":"cisco"}],"cvss":{"score":5.9,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"The FTP service in Cisco AsyncOS on Email Security Appliance (ESA) devices 9.6.0-000 through 9.9.6-026, Web Security Appliance (WSA) devices 9.0.0-162 through 9.5.0-444, and Content Security Management Appliance (SMA) devices allows remote attackers to cause a denial of service via a flood of FTP traffic, aka Bug IDs CSCuz82907, CSCuz84330, and CSCuz86065.","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-2016-6416","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:email_security_appliance","products":["cisco:email_security_appliance","cisco:web_security_appliance"],"type":"denial_of_service","year":"2016"},"n_packages":0,"n_references":5,"next":{"headline":"Cross-site request forgery in n/a","id":"CVE-2016-6417"},"packages":[],"prev":{"headline":"Cisco IOS, IOS XR, and IOS XE IKEv1 Information Disclosure","id":"CVE-2016-6415"},"products":["n/a"],"published":"2016-10-05","related":[{"cvss_score":8.5,"headline":"File upload in n/a","id":"CVE-2014-2119","kev_date_added":null,"published":"2014-03-20"},{"cvss_score":7.8,"headline":"Denial of service in n/a","id":"CVE-2015-6321","kev_date_added":null,"published":"2015-11-06"},{"cvss_score":7.8,"headline":"Denial of service in n/a","id":"CVE-2013-5537","kev_date_added":null,"published":"2013-10-24"},{"cvss_score":7.5,"headline":"Weak cryptography in n/a","id":"CVE-2016-2183","kev_date_added":null,"published":"2016-09-01"},{"cvss_score":6.8,"headline":"Cross-site request forgery in n/a","id":"CVE-2013-3395","kev_date_added":null,"published":"2013-07-02"},{"cvss_score":6.7,"headline":"Cisco Content Security Management Appliance Privilege Escalation Vulnerability","id":"CVE-2021-1447","kev_date_added":null,"published":"2021-05-06"},{"cvss_score":6.5,"headline":"Missing authorization in Cisco Email Security Appliance and Cisco Content Security Management Appliance","id":"CVE-2018-0140","kev_date_added":null,"published":"2018-02-08"}],"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 a denial of service on Cisco Email, Web, and Content Security Appliances by flooding the FTP service with traffic.","url":"https://insights.sbomify.com/CVE-2016-6416/"}
