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-2024-52920 in the wild and no public exploit code.\n\nAffected product: Bitcoin Bitcoin Core. 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-2024-52920/ (Markdown: https://insights.sbomify.com/CVE-2024-52920/index.md)","id":"CVE-2024-52920","markdown":"https://insights.sbomify.com/CVE-2024-52920/index.md","name":"CVE-2024-52920","record":{"aliases":["GHSA-wqx3-8496-4xhc"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Bitcoin Core client","requires_auth":"none","summary":"Remote attackers can cause a denial of service via infinite loop in Bitcoin Core by sending malformed GETDATA messages.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"bitcoin_core","vendor":"bitcoin"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","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-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"Bitcoin Core before 0.20.0 allows remote attackers to cause a denial of service (infinite loop) via a malformed GETDATA message.","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":"Denial of service in n/a","id":"CVE-2024-52920","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"bitcoin:bitcoin_core","products":["bitcoin:bitcoin_core"],"type":"denial_of_service","year":"2024"},"n_packages":0,"n_references":2,"next":{"headline":"Missing authorization in n/a","id":"CVE-2024-52921"},"packages":[],"prev":{"headline":"Integer overflow in n/a","id":"CVE-2024-52919"},"products":["n/a"],"published":"2024-11-18","related":[{"cvss_score":7.5,"headline":"Integer overflow in n/a","id":"CVE-2025-46597","kev_date_added":null,"published":"2026-03-20"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2025-54604","kev_date_added":null,"published":"2025-10-28"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2025-54605","kev_date_added":null,"published":"2025-10-28"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2019-25220","kev_date_added":null,"published":"2024-11-18"},{"cvss_score":7.5,"headline":"Integer overflow in n/a","id":"CVE-2024-52912","kev_date_added":null,"published":"2024-11-18"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2024-52914","kev_date_added":null,"published":"2024-11-18"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2024-52915","kev_date_added":null,"published":"2024-11-18"}],"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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-11-18","vendors":["n/a"]},"summary":"Remote attackers can cause a denial of service via infinite loop in Bitcoin Core by sending malformed GETDATA messages.","url":"https://insights.sbomify.com/CVE-2024-52920/"}
