CVSS: 3.7EPSS: 0%CPEs: 1EXPL: 0CVE-2024-22403 – OAuth2 authorization codes are valid indefinetly in Nextcloud server
https://notcve.org/view.php?id=CVE-2024-22403
Nextcloud server is a self hosted personal cloud system. In affected versions OAuth codes did not expire. When an attacker would get access to an authorization code they could authenticate at any time using the code. As of version 28.0.0 OAuth codes are invalidated after 10 minutes and will no longer be authenticated. To exploit this vulnerability an attacker would need to intercept an OAuth code from a user session. • https://github.com/nextcloud/security-advisories/security/advisories/GHSA-wppc-f5g8-vx36 https://github.com/nextcloud/server/pull/40766 https://hackerone.com/reports/1784162 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/S6PN4GVJ5TZUC6WSG4X3ZA3AMPBEKNAX • CWE-613: Insufficient Session Expiration •
