It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-40660 in the wild and no public exploit code.\n\nAffected product: Opensc Project Opensc. 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-2023-40660/ (Markdown: https://insights.sbomify.com/CVE-2023-40660/index.md)","id":"CVE-2023-40660","markdown":"https://insights.sbomify.com/CVE-2023-40660/index.md","name":"CVE-2023-40660","record":{"aliases":["AZL-31787","AZL-35074","CLSA-2026-1779368985","DEBIAN-CVE-2023-40660","GHSA-7635-x5f9-5458","OESA-2023-1766","OESA-2023-1767","UBUNTU-CVE-2023-40660"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["security_bypass","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"OpenSC smart card library","requires_auth":"none","summary":"Attackers can bypass PIN authentication on smart cards by passing an empty PIN, allowing unauthorized cryptographic operations and system access.","user_interaction":"required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"opensc","vendor":"opensc_project"},{"product":"enterprise_linux","vendor":"redhat"}],"cvss":{"score":6.6,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"A flaw was found in OpenSC packages that allow a potential PIN bypass. When a token/card is authenticated by one process, it can perform cryptographic operations in other processes when an empty zero-length pin is passed. This issue poses a security risk, particularly for OS logon/screen unlock and for small, permanently connected tokens to computers. Additionally, the token can internally track login status. This flaw allows an attacker to gain unauthorized access, carry out malicious actions, or compromise the system without the user's awareness.","ecosystems":[],"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":"Opensc: potential pin bypass when card tracks its own login state","id":"CVE-2023-40660","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"opensc_project:opensc","products":["opensc_project:opensc","redhat:enterprise_linux"],"type":"auth_bypass","year":"2023"},"n_packages":0,"n_references":7,"next":{"headline":"Opensc: multiple memory issues with pkcs15-init (enrollment tool)","id":"CVE-2023-40661"},"packages":[],"prev":{"headline":"Extension - joomboost.com - Reflected XSS in Easy Quick Contact module for Joomla 1.0.0-1.3.0","id":"CVE-2023-40659"},"products":["Red Hat Enterprise Linux 7","Red Hat Enterprise Linux 8","Red Hat Enterprise Linux 9"],"published":"2023-11-06","related":[{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2021-34193","kev_date_added":null,"published":"2023-08-22"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2019-16058","kev_date_added":null,"published":"2019-09-06"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2019-6502","kev_date_added":null,"published":"2019-01-22"},{"cvss_score":7.1,"headline":"Memory corruption in OpenSC","id":"CVE-2023-2977","kev_date_added":null,"published":"2023-06-01"},{"cvss_score":6.8,"headline":"Use after free in n/a","id":"CVE-2019-20792","kev_date_added":null,"published":"2020-04-29"},{"cvss_score":6.8,"headline":"Memory corruption in n/a","id":"CVE-2018-16391","kev_date_added":null,"published":"2018-09-03"},{"cvss_score":6.8,"headline":"Memory corruption in n/a","id":"CVE-2018-16392","kev_date_added":null,"published":"2018-09-03"}],"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-11-06","vendors":["Red Hat"]},"summary":"Attackers can bypass PIN authentication on smart cards by passing an empty PIN, allowing unauthorized cryptographic operations and system access.","url":"https://insights.sbomify.com/CVE-2023-40660/"}
