An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2024-42459 exists.\n\nAffected packages and fixed versions:\n- elliptic (npm): affected from 4.0.0; fixed in 6.5.7\n- elliptic (npm): affected from 4.0.0; fixed in 6.5.7\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-2024-42459/ (Markdown: https://insights.sbomify.com/CVE-2024-42459/index.md)","id":"CVE-2024-42459","markdown":"https://insights.sbomify.com/CVE-2024-42459/index.md","name":"CVE-2024-42459","record":{"aliases":["AZL-47421","DEBIAN-CVE-2024-42459","GHSA-f7q4-pwc6-w24p","UBUNTU-CVE-2024-42459"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js Elliptic library","requires_auth":"none","summary":"Attackers can exploit signature malleability in the Elliptic library by manipulating zero-valued bytes, bypassing signature validation checks.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"elliptic","vendor":"indutny"}],"cvss":{"score":5.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"}],"description":"In the Elliptic package 6.5.6 for Node.js, EDDSA signature malleability occurs because there is a missing signature length check, and thus zero-valued bytes can be removed or appended.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Elliptic's EDDSA missing signature length check","id":"CVE-2024-42459","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"other","year":"2024"},"n_packages":2,"n_references":1,"next":{"headline":"Elliptic's ECDSA missing check for whether leading bit of r and s is zero","id":"CVE-2024-42460"},"packages":[{"ecosystem":"npm","fixed":["6.5.7"],"introduced":["4.0.0"],"last_affected":[],"package":"elliptic","purl":null,"source":"GHSA-f7q4-pwc6-w24p"},{"ecosystem":"npm","fixed":["6.5.7"],"introduced":["4.0.0"],"last_affected":[],"package":"elliptic","purl":"pkg:npm/elliptic","source":"GHSA-f7q4-pwc6-w24p"}],"prev":{"headline":"Security feature bypass in n/a","id":"CVE-2024-42458"},"products":["n/a"],"published":"2024-08-02","related":[{"cvss_score":9.1,"headline":"Elliptic's verify function omits uniqueness validation","id":"CVE-2024-48949","kev_date_added":null,"published":"2024-10-10"},{"cvss_score":7.7,"headline":"Signature Malleabillity in elliptic","id":"CVE-2020-13822","kev_date_added":null,"published":"2020-06-04"},{"cvss_score":6.8,"headline":"Cryptographic Issues","id":"CVE-2020-28498","kev_date_added":null,"published":"2021-02-02"},{"cvss_score":5.3,"headline":"Elliptic's ECDSA missing check for whether leading bit of r and s is zero","id":"CVE-2024-42460","kev_date_added":null,"published":"2024-08-02"},{"cvss_score":4.8,"headline":"Valid ECDSA signatures erroneously rejected in Elliptic","id":"CVE-2024-48948","kev_date_added":null,"published":"2024-10-15"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-11-03","vendors":["n/a"]},"summary":"Attackers can exploit signature malleability in the Elliptic library by manipulating zero-valued bytes, bypassing signature validation checks.","url":"https://insights.sbomify.com/CVE-2024-42459/"}
