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-2021-42759 in the wild and no public exploit code.\n\nAffected product: Fortinet Meru AP. 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-2021-42759/ (Markdown: https://insights.sbomify.com/CVE-2021-42759/index.md)","id":"CVE-2021-42759","markdown":"https://insights.sbomify.com/CVE-2021-42759/index.md","name":"CVE-2021-42759","record":{"aliases":["GHSA-h9rw-2gc4-4x9v"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Fortinet Meru AP","requires_auth":"high_privilege","summary":"Attackers can execute unauthorized code or commands on Fortinet Meru Access Points via crafted CLI commands due to secure design violations.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"fortinet","cpe":[{"product":"meru_firmware","vendor":"fortinet"}],"cvss":{"score":6.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H/E:P/RL:X/RC:C","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"A violation of secure design principles in Fortinet Meru AP version 8.6.1 and below, version 8.5.5 and below allows attacker to execute unauthorized code or commands via crafted cli commands.","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":"Command injection in Fortinet Meru AP","id":"CVE-2021-42759","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"SQL injection in Fortinet FortiWLM","id":"CVE-2021-42760"},"packages":[],"prev":{"headline":"Privilege escalation in Fortinet FortiWLC","id":"CVE-2021-42758"},"products":["Fortinet Meru AP"],"published":"2021-12-09","related":[],"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":"total"},"state":"PUBLISHED","updated":"2024-10-25","vendors":["Fortinet"]},"summary":"Attackers can execute unauthorized code or commands on Fortinet Meru Access Points via crafted CLI commands due to secure design violations.","url":"https://insights.sbomify.com/CVE-2021-42759/"}
