{"id":"CVE-2023-44381","aliases":[],"url":"https://o3.security/vulnerability/CVE-2023-44381","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)","published":"2023-11-29T21:33:16Z","modified":"2023-12-04T15:17:41Z","cvss":{"score":4.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"october/system","fixedVersion":"3.4.15"}],"fix":null,"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2023-12-04T15:17:41Z"}}
