This flaw allows attackers to bypass brute force protection by exploiting the timing of login attempts. By initiating multiple login requests simultaneously, attackers can exceed the configured limits for failed attempts before the system locks them out. This timing loophole enables attackers to make more guesses at passwords than intended, potentially compromising account security on affected systems.","provenance":"source","from":"CVE.org"},"cvss":{"score":6.5,"severity":"MEDIUM","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","provenance":"source","from":"CVE.org CNA"},"epss":{"score":0.00793,"percentile":0.5624,"provenance":"source"},"cwes":[{"id":"CWE-837","name":"Improper Enforcement of a Single, Unique Action"}],"references":[{"url":"https://access.redhat.com/errata/RHSA-2024:6493","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/errata/RHSA-2024:6494","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/errata/RHSA-2024:6495","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/errata/RHSA-2024:6497","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/errata/RHSA-2024:6499","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/errata/RHSA-2024:6500","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/errata/RHSA-2024:6501","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/security/cve/CVE-2024-4629","tags":["vdb-entry","x_refsource_REDHAT"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2276761","tags":["issue-tracking","x_refsource_REDHAT"]},{"url":"https://security.humanativaspa.it/an-analysis-of-the-keycloak-authentication-system/","tags":[]},{"url":"https://github.com/hnsecurity/vulns/blob/main/HNS-2024-09-Keycloak.md","tags":[]}],"priority":{"score":15.8,"factors":[{"name":"EPSS percentile","points":11.25},{"name":"CVSS severity","points":4.55}]},"vendorSlug":"red-hat","affectedVersions":[{"vendor":null,"product":null,"versions":["24.0.3"]},{"vendor":"Red Hat","product":"Red Hat build of Keycloak 22","versions":["all versions"]},{"vendor":"Red Hat","product":"Red Hat build of Keycloak 22","versions":["all versions"]},{"vendor":"Red Hat","product":"Red Hat build of Keycloak 22","versions":["all versions"]},{"vendor":"Red Hat","product":"Red Hat Single Sign-On 7.6 for RHEL 7","versions":["all versions"]},{"vendor":"Red Hat","product":"Red Hat Single Sign-On 7.6 for RHEL 8","versions":["all versions"]},{"vendor":"Red Hat","product":"Red Hat Single Sign-On 7.6 for RHEL 9","versions":["all versions"]},{"vendor":"Red Hat","product":"RHEL-8 based Middleware Containers","versions":["all versions"]}],"affected":[{"ecosystem":"Maven","package":"org.keycloak:keycloak-services","vulnerableRanges":["<22.0.12",">=23.0.0, <24.0.7",">=25.0.0, <25.0.4"],"patched":["22.0.12","24.0.7","25.0.4"],"from":["GHSA-gc7q-jgjv-vjr2"],"provenance":"source"}],"euvd":{"id":"EUVD-2024-2798","exploited":false,"provenance":"source"},"lineage":{"packageHistory":[{"cve":"CVE-2024-2419","published":"2024-04-17","fixed":"24.0.3","kev":false},{"cve":"CVE-2024-3656","published":"2024-10-09","fixed":"24.0.5","kev":false},{"cve":"CVE-2024-4540","published":"2024-06-03","fixed":"24.0.5","kev":false,"link":{"from":"CVE-2024-4540","to":"CVE-2024-4629","relation":"successor","confidence":"low","kind":"sequence","evidence":[{"kind":"version-step","provenance":"source","package":"Maven:org.keycloak:keycloak-services","fromFixed":"24.0.5","toFixed":"24.0.7","daysApart":92}]}},{"cve":"CVE-2024-4629","published":"2024-09-03","fixed":"25.0.4","kev":false},{"cve":"CVE-2024-7341","published":"2024-09-09","fixed":"25.0.5","kev":false,"link":{"from":"CVE-2024-4629","to":"CVE-2024-7341","relation":"successor","confidence":"low","kind":"sequence","evidence":[{"kind":"version-step","provenance":"source","package":"Maven:org.keycloak:keycloak-services","fromFixed":"25.0.4","toFixed":"25.0.5","daysApart":6}]}},{"cve":"CVE-2024-8883","published":"2024-09-19","fixed":"25.0.6","kev":false},{"cve":"CVE-2025-12390","published":"2025-10-28","fixed":"26.0.0","kev":false}],"package":"Maven:org.keycloak:keycloak-services"}}
