Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-33242 exists.\n\nAffected product: Lindell TSS Implementations Wallet. 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-2023-33242/ (Markdown: https://insights.sbomify.com/CVE-2023-33242/index.md)","id":"CVE-2023-33242","markdown":"https://insights.sbomify.com/CVE-2023-33242/index.md","name":"CVE-2023-33242","record":{"aliases":["GHSA-7rw5-c532-37cv"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Crypto wallet library","requires_auth":"low_privilege","summary":"Attackers can extract full ECDSA private keys from crypto wallets by exploiting improper abort handling in Lindell17 TSS implementations.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Halborn","cpe":[{"product":"lindell17","vendor":"lindell17_project"}],"cvss":{"score":9.6,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"}],"description":"Crypto wallets implementing the Lindell17 TSS protocol might allow an attacker to extract the full ECDSA private key by exfiltrating a single bit in every signature attempt (256 in total) because of not adhering to the paper's security proof's assumption regarding handling aborts after a failed signature.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2023-08-15","github_poc":1,"max_poc_stars":4,"metasploit":0,"nuclei":0,"refs":[{"date":"2023-08-15T13:46:48Z","kind":"github_poc","ref":"https://github.com/d0rb/CVE-2023-33242","stars":4,"title":"CVE-2023-33242  PoC"}],"tier":"weaponised"},"has_fix":null,"headline":"Lindell17 TSS Abort Mishandling","id":"CVE-2023-33242","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2023"},"n_packages":0,"n_references":4,"next":{"headline":"Auth bypass in n/a","id":"CVE-2023-33243"},"packages":[],"prev":{"headline":"GG18 / GG20 TSS Beta Parameter Vulnerability","id":"CVE-2023-33241"},"products":["Wallet"],"published":"2023-08-09","related":[],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-10-10","vendors":["Lindell TSS Implementations"]},"summary":"Attackers can extract full ECDSA private keys from crypto wallets by exploiting improper abort handling in Lindell17 TSS implementations.","url":"https://insights.sbomify.com/CVE-2023-33242/"}
