It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-43066 in the wild and no public exploit code.\n\nAffected product: Fortinet Forticlient. 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-2021-43066/ (Markdown: https://insights.sbomify.com/CVE-2021-43066/index.md)","id":"CVE-2021-43066","markdown":"https://insights.sbomify.com/CVE-2021-43066/index.md","name":"CVE-2021-43066","record":{"aliases":["GHSA-726x-mfp5-rvmh"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Fortinet FortiClient Windows","requires_auth":"low_privilege","summary":"An attacker can escalate privileges on Windows systems by exploiting improper file path control in the FortiClient MSI installer.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"fortinet","cpe":[{"product":"forticlient","vendor":"fortinet"}],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:H/A:H/E:H/RL:U/RC:C","version":"3.1"},"cwes":[{"id":"CWE-668","name":"Exposure of Resource to Wrong Sphere"}],"description":"A external control of file name or path in Fortinet FortiClientWindows version 7.0.2 and below, version 6.4.6 and below, version 6.2.9 and below, version 6.0.10 and below allows attacker to escalate privilege via the MSI installer.","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":"Privilege escalation in Fortinet FortiClientWindows","id":"CVE-2021-43066","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"fortinet:forticlient","products":["fortinet:forticlient"],"type":"privilege_escalation","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in Fortinet FortiAuthenticator","id":"CVE-2021-43067"},"packages":[],"prev":{"headline":"Privilege escalation in Fortinet FortiNAC","id":"CVE-2021-43065"},"products":["Fortinet FortiClientWindows"],"published":"2022-05-11","related":[{"cvss_score":9.8,"headline":"Privilege escalation in Fortinet FortiClientWindows","id":"CVE-2019-17658","kev_date_added":null,"published":"2020-03-12"},{"cvss_score":9.4,"headline":"Code injection in FortiClientLinux","id":"CVE-2023-45590","kev_date_added":null,"published":"2024-04-09"},{"cvss_score":8.8,"headline":"Information disclosure in FortiClient SSLVPN Client for Linux","id":"CVE-2017-14184","kev_date_added":null,"published":"2017-12-15"},{"cvss_score":8.8,"headline":"Privilege escalation in Fortinet FortiClient","id":"CVE-2016-8493","kev_date_added":null,"published":"2017-06-26"},{"cvss_score":8.6,"headline":"Privilege escalation in FortiClientLinux","id":"CVE-2020-15934","kev_date_added":null,"published":"2024-12-19"},{"cvss_score":8.6,"headline":"Path traversal in FortiClientWindows","id":"CVE-2019-5589","kev_date_added":null,"published":"2019-05-28"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-10-22","vendors":["Fortinet"]},"summary":"An attacker can escalate privileges on Windows systems by exploiting improper file path control in the FortiClient MSI installer.","url":"https://insights.sbomify.com/CVE-2021-43066/"}
