Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-40545 in the wild and no public exploit code.\n\nAffected product: PingFederate. 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-2023-40545/ (Markdown: https://insights.sbomify.com/CVE-2023-40545/index.md)","id":"CVE-2023-40545","markdown":"https://insights.sbomify.com/CVE-2023-40545/index.md","name":"CVE-2023-40545","record":{"aliases":["GHSA-37j2-h4x2-rp3v"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"PingFederate identity server","requires_auth":"low_privilege","summary":"Attackers can bypass authentication in PingFederate OAuth client_secret_jwt flows via crafted requests, requiring immediate patching.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Ping Identity","cpe":[{"product":"pingfederate","vendor":"pingidentity"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"Authentication bypass when an OAuth2 Client is using client_secret_jwt as its authentication method on affected 11.3 versions via specially crafted requests.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"PingFederate OAuth client_secret_jwt Authentication Bypass","id":"CVE-2023-40545","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2023"},"n_packages":0,"n_references":3,"next":{"headline":"Shim: out-of-bounds read printing error messages","id":"CVE-2023-40546"},"packages":[],"prev":{"headline":"Westermo Lynx Cleartext Transmission of Sensitive Information","id":"CVE-2023-40544"},"products":["PingFederate"],"published":"2024-02-06","related":[{"cvss_score":9.8,"headline":"The Authentication API in Ping Identity PingFederate before 10.3 mishandles certain aspects of external password management.","id":"CVE-2021-40329","kev_date_added":null,"published":"2021-09-27"},{"cvss_score":8.1,"headline":"Authentication Bypass via HTML Form \u0026 Identifier First Adapter","id":"CVE-2023-37283","kev_date_added":null,"published":"2023-10-25"},{"cvss_score":7.7,"headline":"Misconfiguration of RSA padding for offline MFA in the PingID Adapter for PingFederate.","id":"CVE-2022-40722","kev_date_added":null,"published":"2023-04-25"},{"cvss_score":7.5,"headline":"Admin Console Denial of Service via Java class enumeration","id":"CVE-2023-39219","kev_date_added":null,"published":"2023-10-25"},{"cvss_score":7.5,"headline":"XML external entity in n/a","id":"CVE-2021-41770","kev_date_added":null,"published":"2021-10-07"},{"cvss_score":6.5,"headline":"Configuration-based MFA Bypass in PingID RADIUS PCV.","id":"CVE-2022-40723","kev_date_added":null,"published":"2023-04-25"}],"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":"2024-08-22","vendors":["Ping Identity"]},"summary":"Attackers can bypass authentication in PingFederate OAuth client_secret_jwt flows via crafted requests, requiring immediate patching.","url":"https://insights.sbomify.com/CVE-2023-40545/"}
