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-2016-6909 in the wild and no public exploit code.\n\nAffected product: Fortinet Fortios. 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-2016-6909/ (Markdown: https://insights.sbomify.com/CVE-2016-6909/index.md)","id":"CVE-2016-6909","markdown":"https://insights.sbomify.com/CVE-2016-6909/index.md","name":"CVE-2016-6909","record":{"aliases":["GHSA-f3wq-8j4r-5p8m"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Fortinet FortiOS","requires_auth":"none","summary":"Remote attackers can execute arbitrary code via a crafted HTTP request due to a buffer overflow in the Cookie parser of FortiOS.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"fortios","vendor":"fortinet"},{"product":"fortiswitch","vendor":"fortinet"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Buffer overflow in the Cookie parser in Fortinet FortiOS 4.x before 4.1.11, 4.2.x before 4.2.13, and 4.3.x before 4.3.9 and FortiSwitch before 3.4.3 allows remote attackers to execute arbitrary code via a crafted HTTP request, aka EGREGIOUSBLUNDER.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2016-08-19","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2016-08-19","kind":"exploitdb","ref":"40276","stars":null,"title":"Fortigate Firewalls - 'EGREGIOUSBLUNDER' Remote Code Execution"}],"tier":"poc_unverified"},"has_fix":null,"headline":"Memory corruption in n/a","id":"CVE-2016-6909","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"fortinet:fortios","products":["fortinet:fortios"],"type":"memory_corruption","year":"2016"},"n_packages":0,"n_references":6,"next":{"headline":"Information disclosure in n/a","id":"CVE-2016-6910"},"packages":[],"prev":{"headline":"Open redirect in n/a","id":"CVE-2016-6908"},"products":["n/a"],"published":"2016-08-24","related":[{"cvss_score":9.8,"headline":"Fortinet Multiple Products Format String","id":"CVE-2024-23113","kev_date_added":"2024-10-09","published":"2024-02-15"},{"cvss_score":9.8,"headline":"Fortinet Multiple Products Authentication Bypass","id":"CVE-2022-40684","kev_date_added":"2022-10-11","published":"2022-10-18"},{"cvss_score":9.6,"headline":"Fortinet FortiOS and FortiProxy Authentication Bypass","id":"CVE-2024-55591","kev_date_added":"2025-01-14","published":"2025-01-14"},{"cvss_score":9.6,"headline":"Fortinet FortiOS Out-of-Bound Write","id":"CVE-2024-21762","kev_date_added":"2024-02-09","published":"2024-02-09"},{"cvss_score":9.3,"headline":"Fortinet FortiOS Heap-Based Buffer Overflow","id":"CVE-2022-42475","kev_date_added":"2022-12-13","published":"2023-01-02"},{"cvss_score":9.2,"headline":"Fortinet FortiOS and FortiProxy SSL-VPN Heap-Based Buffer Overflow","id":"CVE-2023-27997","kev_date_added":"2023-06-13","published":"2023-06-13"},{"cvss_score":9.1,"headline":"Fortinet Multiple Products Improper Verification of Cryptographic Signature","id":"CVE-2025-59718","kev_date_added":"2025-12-16","published":"2025-12-09"}],"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)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code via a crafted HTTP request due to a buffer overflow in the Cookie parser of FortiOS.","url":"https://insights.sbomify.com/CVE-2016-6909/"}
