{"cve":"CVE-2023-37471","nvd":{"published":"2023-07-20T17:15:10.917","modified":"2026-06-17T06:08:17.127","status":"Modified","description":"Open Access Management (OpenAM) is an access management solution that includes Authentication, SSO, Authorization, Federation, Entitlements and Web Services Security. OpenAM up to version 14.7.2 does not properly validate the signature of SAML responses received as part of the SAMLv1.x Single Sign-On process. Attackers can use this fact to impersonate any OpenAM user, including the administrator, by sending a specially crafted SAML response to the SAMLPOSTProfileServlet servlet. This problem has been patched in  OpenAM 14.7.3-SNAPSHOT and later. User unable to upgrade should comment servlet `SAMLPOSTProfileServlet` from their pom file. See the linked GHSA for details.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-287"],"references":["https://github.com/OpenIdentityPlatform/OpenAM/commit/7c18543d126e8a567b83bb4535631825aaa9d742","https://github.com/OpenIdentityPlatform/OpenAM/pull/624","https://github.com/OpenIdentityPlatform/OpenAM/security/advisories/GHSA-4mh8-9wq6-rjxg","https://github.com/OpenIdentityPlatform/OpenAM/commit/7c18543d126e8a567b83bb4535631825aaa9d742","https://github.com/OpenIdentityPlatform/OpenAM/pull/624"],"products":["openidentityplatform:openam"],"source":"nvd","synced_at":"2026-10-19T21:38:35.729974749+00:00"},"epss":{"cve":"CVE-2023-37471","score":0.0126,"percentile":0.69605,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-4mh8-9wq6-rjxg","url":"https://osv.dev/vulnerability/GHSA-4mh8-9wq6-rjxg","summary":"OpenAM vulnerable to user impersonation using SAMLv1.x SSO process","modified":"2026-09-10T03:49:42.565570540Z","packages":[{"ecosystem":"Maven","name":"org.openidentityplatform.openam:openam-federation-library","purl":"pkg:maven/org.openidentityplatform.openam/openam-federation-library","ranges":["<14.7.3"],"fixed":["14.7.3"]}]}],"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).
