An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2022-40684 in the wild since at least 11 Oct 2022, including in ransomware campaigns.\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-2022-40684/ (Markdown: https://insights.sbomify.com/CVE-2022-40684/index.md)","id":"CVE-2022-40684","markdown":"https://insights.sbomify.com/CVE-2022-40684/index.md","name":"CVE-2022-40684","record":{"aliases":["GHSA-m3wm-rjvf-m778"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Fortinet network security","requires_auth":"none","summary":"Unauthenticated attackers can bypass authentication to perform administrative operations on Fortinet devices via crafted HTTP requests.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"fortinet","cpe":[{"product":"fortios","vendor":"fortinet"},{"product":"fortiproxy","vendor":"fortinet"},{"product":"fortiswitchmanager","vendor":"fortinet"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:F/RL:U/RC:C","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"An authentication bypass using an alternate path or channel [CWE-288] in Fortinet FortiOS version 7.2.0 through 7.2.1 and 7.0.0 through 7.0.6, FortiProxy version 7.2.0 and version 7.0.0 through 7.0.6 and FortiSwitchManager version 7.2.0 and 7.0.0 allows an unauthenticated atttacker to perform operations on the administrative interface via specially crafted HTTP or HTTPS requests.","ecosystems":[],"exploits":{"exploitdb":2,"first_seen":"2022-10-10","github_poc":31,"max_poc_stars":359,"metasploit":1,"nuclei":1,"refs":[{"date":"2022-10-13T14:24:12Z","kind":"github_poc","ref":"https://github.com/horizon3ai/CVE-2022-40684","stars":359,"title":"A proof of concept exploit for CVE-2022-40684 affecting Fortinet FortiOS, FortiProxy, and FortiSwitchManager"},{"date":"2022-10-13T18:13:59Z","kind":"github_poc","ref":"https://github.com/carlosevieira/CVE-2022-40684","stars":87,"title":"PoC for CVE-2022-40684 -
