Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-43164 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2021-43164/ (Markdown: https://insights.sbomify.com/CVE-2021-43164/index.md)","id":"CVE-2021-43164","markdown":"https://insights.sbomify.com/CVE-2021-43164/index.md","name":"CVE-2021-43164","record":{"aliases":["GHSA-xx25-w9gj-928r"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Ruijie RG-EW Router","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary code on Ruijie RG-EW routers via a command injection flaw in the wireless API update function.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"reyeeos","vendor":"ruijienetworks"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"A Remote Code Execution (RCE) vulnerability exists in Ruijie Networks Ruijie RG-EW Series Routers up to ReyeeOS 1.55.1915 / EW_3.0(1)B11P55 via the updateVersion function in /cgi-bin/luci/api/wireless.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2022-05-11","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2022-05-11","kind":"exploitdb","ref":"50930","stars":null,"title":"Ruijie Reyee Mesh Router - Remote Code Execution (RCE) (Authenticated)"}],"tier":"poc_unverified"},"has_fix":null,"headline":"Command injection in n/a","id":"CVE-2021-43164","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Security feature bypass in n/a","id":"CVE-2021-43171"},"packages":[],"prev":{"headline":"Command injection in n/a","id":"CVE-2021-43163"},"products":["n/a"],"published":"2022-05-04","related":[{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2021-43163","kev_date_added":null,"published":"2022-05-04"},{"cvss_score":8.8,"headline":"Command injection in n/a","id":"CVE-2021-43159","kev_date_added":null,"published":"2022-05-04"},{"cvss_score":8.8,"headline":"Command injection in n/a","id":"CVE-2021-43160","kev_date_added":null,"published":"2022-05-04"},{"cvss_score":8.8,"headline":"Command injection in n/a","id":"CVE-2021-43161","kev_date_added":null,"published":"2022-05-04"},{"cvss_score":8.8,"headline":"Command injection in n/a","id":"CVE-2021-43162","kev_date_added":null,"published":"2022-05-04"}],"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":"2026-07-09","vendors":["n/a"]},"summary":"Attackers can execute arbitrary code on Ruijie RG-EW routers via a command injection flaw in the wireless API update function.","url":"https://insights.sbomify.com/CVE-2021-43164/"}
