Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-20675 in the wild and no public exploit code.\n\nAffected product: M-System DL8 series. 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-2021-20675/ (Markdown: https://insights.sbomify.com/CVE-2021-20675/index.md)","id":"CVE-2021-20675","markdown":"https://insights.sbomify.com/CVE-2021-20675/index.md","name":"CVE-2021-20675","record":{"aliases":["GHSA-c5hr-whfp-6f78"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial data logger","requires_auth":"low_privilege","summary":"Remote authenticated attackers can cause a denial of service condition in M-System DL8 series industrial data loggers.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"dl8-a_firmware","vendor":"m-system"},{"product":"dl8-b_firmware","vendor":"m-system"},{"product":"dl8-c_firmware","vendor":"m-system"},{"product":"dl8-d_firmware","vendor":"m-system"},{"product":"dl8-e_firmware","vendor":"m-system"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"M-System DL8 series (type A (DL8-A) versions prior to Ver3.0, type B (DL8-B) versions prior to Ver3.0, type C (DL8-C) versions prior to Ver3.0, type D (DL8-D) versions prior to Ver3.0, and type E (DL8-E) versions prior to Ver3.0) allows remote authenticated attackers to cause a denial of service (DoS) condition 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":"Denial of service in M-System DL8 series","id":"CVE-2021-20675","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Auth bypass in M-System DL8 series","id":"CVE-2021-20676"},"packages":[],"prev":{"headline":"Privilege escalation in Installer of MagicConnect Client program","id":"CVE-2021-20674"},"products":["M-System DL8 series"],"published":"2021-03-18","related":[{"cvss_score":4.3,"headline":"Auth bypass in M-System DL8 series","id":"CVE-2021-20676","kev_date_added":null,"published":"2021-03-18"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["M-System Co., Ltd."]},"summary":"Remote authenticated attackers can cause a denial of service condition in M-System DL8 series industrial data loggers.","url":"https://insights.sbomify.com/CVE-2021-20675/"}
