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-2021-33840 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-2021-33840/ (Markdown: https://insights.sbomify.com/CVE-2021-33840/index.md)","id":"CVE-2021-33840","markdown":"https://insights.sbomify.com/CVE-2021-33840/index.md","name":"CVE-2021-33840","record":{"aliases":["GHSA-r75x-rqwg-mqhc"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Luca server","requires_auth":"none","summary":"Remote attackers can cause denial of service by inserting fake records due to missing digital signatures on phone number data.","user_interaction":"not_required","vuln_class":"business_logic"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"luca","vendor":"luca-app"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-345","name":"Insufficient Verification of Data Authenticity"}],"description":"The server in Luca through 1.1.14 allows remote attackers to cause a denial of service (insertion of many fake records related to COVID-19) because Phone Number data lacks a digital signature.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Business logic in n/a","id":"CVE-2021-33840","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"business_logic","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Circutor SGE-PLC1000 OS command Injection","id":"CVE-2021-33841"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2021-33839"},"products":["n/a"],"published":"2021-06-03","related":[{"cvss_score":7.5,"headline":"Information disclosure in n/a","id":"CVE-2021-33838","kev_date_added":null,"published":"2021-06-03"},{"cvss_score":7.5,"headline":"Information disclosure in n/a","id":"CVE-2021-33839","kev_date_added":null,"published":"2021-06-03"}],"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":"2024-08-03","vendors":["n/a"]},"summary":"Remote attackers can cause denial of service by inserting fake records due to missing digital signatures on phone number data.","url":"https://insights.sbomify.com/CVE-2021-33840/"}
