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-2023-39666 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-2023-39666/ (Markdown: https://insights.sbomify.com/CVE-2023-39666/index.md)","id":"CVE-2023-39666","markdown":"https://insights.sbomify.com/CVE-2023-39666/index.md","name":"CVE-2023-39666","record":{"aliases":["GHSA-8wv2-9v5c-9g5q"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"D-Link router","requires_auth":"none","summary":"Buffer overflows in D-Link DIR-842 routers allow attackers to execute arbitrary code or cause denial of service via crafted parameters.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"dir-842_firmware","vendor":"dlink"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"D-Link DIR-842 fw_revA_1-02_eu_multi_20151008 was discovered to contain multiple buffer overflows in the fgets function via the acStack_120 and acStack_220 parameters.","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":"Memory corruption in n/a","id":"CVE-2023-39666","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":3,"next":{"headline":"Memory corruption in n/a","id":"CVE-2023-39667"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2023-39665"},"products":["n/a"],"published":"2023-08-18","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-8962","kev_date_added":null,"published":"2020-02-13"},{"cvss_score":8.8,"headline":"Auth bypass in DIR-842","id":"CVE-2020-15632","kev_date_added":null,"published":"2020-07-23"}],"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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-10-07","vendors":["n/a"]},"summary":"Buffer overflows in D-Link DIR-842 routers allow attackers to execute arbitrary code or cause denial of service via crafted parameters.","url":"https://insights.sbomify.com/CVE-2023-39666/"}
