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-2022-44797 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/btcsuite/btcd (Go): affected all versions; fixed in 0.23.2\n- github.com/btcsuite/btcd (Go): affected all versions; fixed in 0.23.2\n- github.com/btcsuite/btcd (Go): affected all versions; fixed in 0.23.2\n- github.com/lightningnetwork/lnd (Go): affected all versions; fixed in 0.15.2-beta\n- github.com/lightningnetwork/lnd (Go): affected all versions; fixed in 0.15.2-beta\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-2022-44797/ (Markdown: https://insights.sbomify.com/CVE-2022-44797/index.md)","id":"CVE-2022-44797","markdown":"https://insights.sbomify.com/CVE-2022-44797/index.md","name":"CVE-2022-44797","record":{"aliases":["GHSA-2chg-86hq-7w38","GO-2022-1098","UBUNTU-CVE-2022-44797"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Bitcoin full node","requires_auth":"none","summary":"Attackers can cause a denial of service in btcd and lnd by exploiting improper witness size validation.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"btcd","vendor":"btcd_project"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"btcd before 0.23.2, as used in Lightning Labs lnd before 0.15.2-beta and other Bitcoin-related products, mishandles witness size checking.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"btcd mishandles witness size checking","id":"CVE-2022-44797","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"denial_of_service","year":"2022"},"n_packages":5,"n_references":4,"next":{"headline":"Missing authorization in n/a","id":"CVE-2022-44801"},"packages":[{"ecosystem":"Go","fixed":["0.23.2"],"introduced":["0"],"last_affected":[],"package":"github.com/btcsuite/btcd","purl":null,"source":"GHSA-2chg-86hq-7w38"},{"ecosystem":"Go","fixed":["0.23.2"],"introduced":["0"],"last_affected":[],"package":"github.com/btcsuite/btcd","purl":"pkg:golang/github.com/btcsuite/btcd","source":"GHSA-2chg-86hq-7w38"},{"ecosystem":"Go","fixed":["0.23.2"],"introduced":["0"],"last_affected":[],"package":"github.com/btcsuite/btcd","purl":"pkg:golang/github.com/btcsuite/btcd","source":"GO-2022-1098"},{"ecosystem":"Go","fixed":["0.15.2-beta"],"introduced":["0"],"last_affected":[],"package":"github.com/lightningnetwork/lnd","purl":null,"source":"GHSA-2chg-86hq-7w38"},{"ecosystem":"Go","fixed":["0.15.2-beta"],"introduced":["0"],"last_affected":[],"package":"github.com/lightningnetwork/lnd","purl":"pkg:golang/github.com/lightningnetwork/lnd","source":"GHSA-2chg-86hq-7w38"}],"prev":{"headline":"Weak cryptography in n/a","id":"CVE-2022-44796"},"products":["n/a"],"published":"2022-11-07","related":[{"cvss_score":8.2,"headline":"Witness Block Parsing DoS Vulnerability in lnd","id":"CVE-2022-39389","kev_date_added":null,"published":"2022-11-17"},{"cvss_score":7.5,"headline":"btcd susceptible to consensus failures","id":"CVE-2024-34478","kev_date_added":null,"published":"2024-05-05"},{"cvss_score":7.4,"headline":"btcd did not correctly re-implement Bitcoin Core's \"FindAndDelete()\" functionality","id":"CVE-2024-38365","kev_date_added":null,"published":"2024-10-11"}],"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":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-05-01","vendors":["n/a"]},"summary":"Attackers can cause a denial of service in btcd and lnd by exploiting improper witness size validation.","url":"https://insights.sbomify.com/CVE-2022-44797/"}
