{"cve":"CVE-2025-24032","nvd":{"published":"2025-02-10T16:15:39.153","modified":"2026-06-17T08:57:55.607","status":"Deferred","description":"PAM-PKCS#11 is a Linux-PAM login module that allows a X.509 certificate based user login. Prior to version 0.6.13, if cert_policy is set to none (the default value), then pam_pkcs11 will only check if the user is capable of logging into the token. An attacker may create a different token with the user's public data (e.g. the user's certificate) and a PIN known to the attacker. If no signature with the private key is required, then the attacker may now login as user with that created token. The default to *not* check the private key's signature has been changed with commit commi6638576892b59a99389043c90a1e7dd4d783b921, so that all versions starting with pam_pkcs11-0.6.0 should be affected. As a workaround, in `pam_pkcs11.conf`, set at least `cert_policy = signature;`.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:L/SC:L/SI:L/SA:L","score":9.2},"cvss_v3":null,"cwes":["CWE-287"],"references":["https://github.com/OpenSC/pam_pkcs11/commit/470263258d1ac59c5eade439c4d9caba0097e6e6","https://github.com/OpenSC/pam_pkcs11/commit/b665b287ff955bbbd9539252ff9f9e2754c3fb48","https://github.com/OpenSC/pam_pkcs11/commit/d9530167966a77115db6e885d459382a2e52ee9e","https://github.com/OpenSC/pam_pkcs11/releases/tag/pam_pkcs11-0.6.13","https://github.com/OpenSC/pam_pkcs11/security/advisories/GHSA-8r8p-7mgp-vf56"],"products":[],"source":"nvd","synced_at":"2026-10-19T21:59:18.731010617+00:00"},"epss":{"cve":"CVE-2025-24032","score":0.00712,"percentile":0.53626,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
