{"id":"GHSA-27xw-p8v6-9jjr","summary":"Spring Security vulnerable to Authorization Bypass","details":"Spring Security versions 5.1.x prior to 5.1.2 contain an authorization bypass vulnerability during JWT issuer validation. In order to be impacted, the same private key for an honest issuer and a malicious user must be used when signing JWTs. In that case, a malicious user could fashion signed JWTs with the malicious issuer URL that may be granted for the honest issuer.","aliases":["CVE-2018-15801"],"modified":"2024-03-14T21:16:03.663372Z","published":"2018-12-20T22:01:31Z","database_specific":{"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2020-06-16T20:51:43Z","nvd_published_at":"2018-12-19T22:29:00Z","cwe_ids":["CWE-345"]},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2018-15801"},{"type":"WEB","url":"https://github.com/spring-projects/spring-security/commit/c70b65c5df0e170a2d34d812b83db0b7bc71ea25"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-27xw-p8v6-9jjr"},{"type":"PACKAGE","url":"https://github.com/spring-projects/spring-security"},{"type":"WEB","url":"https://pivotal.io/security/cve-2018-15801"}],"affected":[{"package":{"name":"org.springframework.security:spring-security-core","ecosystem":"Maven","purl":"pkg:maven/org.springframework.security/spring-security-core"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.1.0"},{"fixed":"5.1.2"}]}],"versions":["5.1.0.RELEASE","5.1.1.RELEASE"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2018/12/GHSA-27xw-p8v6-9jjr/GHSA-27xw-p8v6-9jjr.json"}},{"package":{"name":"org.springframework.security:spring-security-oauth2-jose","ecosystem":"Maven","purl":"pkg:maven/org.springframework.security/spring-security-oauth2-jose"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.1.0"},{"fixed":"5.1.2"}]}],"versions":["5.1.0.RELEASE","5.1.1.RELEASE"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2018/12/GHSA-27xw-p8v6-9jjr/GHSA-27xw-p8v6-9jjr.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N"}]}
