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-2020-25366 in the wild and no public exploit code.\n\nAffected product: Dlink Dir-823g Firmware. 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-2020-25366/ (Markdown: https://insights.sbomify.com/CVE-2020-25366/index.md)","id":"CVE-2020-25366","markdown":"https://insights.sbomify.com/CVE-2020-25366/index.md","name":"CVE-2020-25366","record":{"aliases":["GHSA-rpw2-pg2j-mxph"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"D-Link router","requires_auth":"none","summary":"Attackers can cause a denial of service on D-Link DIR-823G routers via the firmware upload CGI script due to missing authorization checks.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"dir-823g_firmware","vendor":"dlink"}],"cvss":{"score":9.1,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"An issue in the component /cgi-bin/upload_firmware.cgi of D-Link DIR-823G REVA1 1.02B05 allows attackers to cause a denial of service (DoS) via unspecified vectors.","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":"Missing authorization in n/a","id":"CVE-2020-25366","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"dlink:dir-823g_firmware","products":["dlink:dir-823g_firmware"],"type":"missing_authorization","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Command injection in n/a","id":"CVE-2020-25367"},"packages":[],"prev":{"headline":"SQL injection in n/a","id":"CVE-2020-25362"},"products":["n/a"],"published":"2021-11-04","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-43235","kev_date_added":null,"published":"2023-09-21"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-43241","kev_date_added":null,"published":"2023-09-21"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-26612","kev_date_added":null,"published":"2023-06-29"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2023-26613","kev_date_added":null,"published":"2023-06-29"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-26616","kev_date_added":null,"published":"2023-06-29"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-29665","kev_date_added":null,"published":"2023-04-17"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2022-44201","kev_date_added":null,"published":"2022-11-22"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-07-09","vendors":["n/a"]},"summary":"Attackers can cause a denial of service on D-Link DIR-823G routers via the firmware upload CGI script due to missing authorization checks.","url":"https://insights.sbomify.com/CVE-2020-25366/"}
