{"id":"GHSA-q22j-5r3g-9hmh","summary":"October CMS safe mode bypass using Page template injection","details":"### Impact\n\nAn authenticated backend user with the `editor.cms_pages`, `editor.cms_layouts`, or `editor.cms_partials` permissions who would normally not be permitted to provide PHP code to be executed by the CMS due to `cms.safe_mode` being enabled can craft a special request to include PHP code in the CMS template.\n\nThis is not a problem for anyone who trusts their users with those permissions to usually write & manage PHP within the CMS by not having `cms.safe_mode` enabled. Still, it would be a problem for anyone relying on `cms.safe_mode` to ensure that users with those permissions in production do not have access to write and execute arbitrary PHP.\n\n### Patches\n\nThis issue has been patched in v3.4.15.\n\n### Workarounds\n\nAs a workaround, remove the specified permissions from untrusted users.\n\n### References\n\nCredits to:\n- [Vasiliy Bodrov](https://github.com/whatev3n)\n\n### For more information\nIf you have any questions or comments about this advisory:\n* Email us at [hello@octobercms.com](mailto:hello@octobercms.com)","aliases":["CVE-2023-44381"],"modified":"2023-12-04T15:17:41Z","published":"2023-11-29T21:33:16Z","database_specific":{"github_reviewed_at":"2023-11-29T21:33:16Z","nvd_published_at":"2023-12-01T22:15:09Z","cwe_ids":["CWE-94"],"severity":"MODERATE","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/octobercms/october/security/advisories/GHSA-q22j-5r3g-9hmh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-44381"},{"type":"PACKAGE","url":"https://github.com/octobercms/october"}],"affected":[{"package":{"name":"october/system","ecosystem":"Packagist","purl":"pkg:composer/october/system"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.0.0"},{"fixed":"3.4.15"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2023/11/GHSA-q22j-5r3g-9hmh/GHSA-q22j-5r3g-9hmh.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:N"}]}
