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-2021-31702 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-2021-31702/ (Markdown: https://insights.sbomify.com/CVE-2021-31702/index.md)","id":"CVE-2021-31702","markdown":"https://insights.sbomify.com/CVE-2021-31702/index.md","name":"CVE-2021-31702","record":{"aliases":["GHSA-vv38-xhh2-74q7"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Frontier ichris","requires_auth":"none","summary":"An attacker can cause a denial of service in Frontier ichris by sending repeated DNS requests via the HTTP Host header.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ichris","vendor":"frontiersoftware"}],"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":[],"description":"Frontier ichris through 5.18 mishandles making a DNS request for the hostname in the HTTP Host header, as demonstrated by submitting 127.0.0.1 multiple times for DoS.","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 n/a","id":"CVE-2021-31702","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"File upload in n/a","id":"CVE-2021-31703"},"packages":[],"prev":{"headline":"Other in n/a","id":"CVE-2021-31701"},"products":["n/a"],"published":"2021-05-29","related":[{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2021-31703","kev_date_added":null,"published":"2021-05-29"}],"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":["n/a"]},"summary":"An attacker can cause a denial of service in Frontier ichris by sending repeated DNS requests via the HTTP Host header.","url":"https://insights.sbomify.com/CVE-2021-31702/"}
