{"id":"GHSA-6cq5-8cj7-g558","summary":"CodeIgniter4 Potential Session Handlers Vulnerability","details":"### Impact\nWhen an application uses (1) multiple session cookies (e.g., one for user pages and one for admin pages) and (2)  a session handler is set to `DatabaseHandler`, `MemcachedHandler`, or `RedisHandler`, then if an attacker gets one session cookie (e.g., one for user pages), they may be able to access pages that require another session cookie (e.g., for admin pages).\n\n### Patches\nUpgrade to version 4.2.11 or later.\n\n### Workarounds\n- Use only one session cookie.\n\n### References\n- https://codeigniter4.github.io/userguide/libraries/sessions.html#session-drivers\n\n### For more information\nIf you have any questions or comments about this advisory:\n* Open an issue in [codeigniter4/CodeIgniter4](https://github.com/codeigniter4/CodeIgniter4/issues)\n* Email us at [SECURITY.md](https://github.com/codeigniter4/CodeIgniter4/blob/develop/SECURITY.md)\n","aliases":["BIT-codeigniter-2022-46170","CVE-2022-46170"],"modified":"2023-12-06T01:02:43.191201Z","published":"2022-12-22T20:01:18Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2022-12-22T20:01:18Z","nvd_published_at":"2022-12-22T19:15:00Z","cwe_ids":["CWE-287"],"severity":"HIGH"},"references":[{"type":"WEB","url":"https://github.com/codeigniter4/CodeIgniter4/security/advisories/GHSA-6cq5-8cj7-g558"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-46170"},{"type":"WEB","url":"https://github.com/codeigniter4/CodeIgniter4/commit/f9fb6574fbeb5a4aa63f7ea87296523e10db9328"},{"type":"WEB","url":"https://codeigniter4.github.io/userguide/libraries/sessions.html#session-drivers"},{"type":"WEB","url":"https://github.com/FriendsOfPHP/security-advisories/blob/master/codeigniter4/framework/CVE-2022-46170.yaml"},{"type":"PACKAGE","url":"https://github.com/codeigniter4/CodeIgniter4"}],"affected":[{"package":{"name":"codeigniter4/framework","ecosystem":"Packagist","purl":"pkg:composer/codeigniter4/framework"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.2.11"}]}],"versions":["4.0.0","4.0.0-rc.4","v4.0.0-alpha.3","v4.0.0-alpha.4","v4.0.0-alpha.5","v4.0.0-beta.1","v4.0.0-beta.2","v4.0.0-beta.3","v4.0.0-beta.4","v4.0.0-rc.1","v4.0.0-rc.2","v4.0.0-rc.2.1","v4.0.0-rc.3","v4.0.1","v4.0.2","v4.0.3","v4.0.4","v4.0.5","v4.1.0","v4.1.1","v4.1.2","v4.1.3","v4.1.4","v4.1.5","v4.1.6","v4.1.7","v4.1.8","v4.1.9","v4.2.0","v4.2.1","v4.2.10","v4.2.2","v4.2.3","v4.2.4","v4.2.5","v4.2.6","v4.2.7","v4.2.8","v4.2.9"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/12/GHSA-6cq5-8cj7-g558/GHSA-6cq5-8cj7-g558.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L"}]}
