{"id":"CVE-2017-16941","details":"October CMS through 1.0.428 does not prevent use of .htaccess in themes, which allows remote authenticated users to execute arbitrary PHP code by downloading a theme ZIP archive from /backend/cms/themes, and then uploading and importing a modified archive with two new files: a .php file and a .htaccess file. NOTE: the vendor says \"I don't think [an attacker able to login to the system under an account that has access to manage/upload themes] is a threat model that we need to be considering.","modified":"2026-04-10T03:57:51.953512Z","published":"2017-11-25T05:29:00.210Z","references":[{"type":"REPORT","url":"https://github.com/octobercms/october/issues/3257"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/octobercms/october","events":[{"introduced":"0"},{"last_affected":"a3b93f1a0b84c14b238c464a1eb93801efea06d6"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"1.0.428"}]}}],"versions":["v1.0.319","v1.0.320","v1.0.321","v1.0.322","v1.0.323","v1.0.324","v1.0.325","v1.0.326","v1.0.327","v1.0.328","v1.0.329","v1.0.330","v1.0.331","v1.0.333","v1.0.334","v1.0.338","v1.0.340","v1.0.341","v1.0.342","v1.0.343","v1.0.344","v1.0.345","v1.0.346","v1.0.351","v1.0.352","v1.0.353","v1.0.354","v1.0.355","v1.0.356","v1.0.358","v1.0.359","v1.0.360","v1.0.361","v1.0.362","v1.0.363","v1.0.364","v1.0.365","v1.0.366","v1.0.367","v1.0.370","v1.0.371","v1.0.372","v1.0.373","v1.0.374","v1.0.375","v1.0.376","v1.0.377","v1.0.378","v1.0.379","v1.0.380","v1.0.381","v1.0.382","v1.0.383","v1.0.384","v1.0.385","v1.0.386","v1.0.387","v1.0.388","v1.0.389","v1.0.390","v1.0.391","v1.0.392","v1.0.393","v1.0.394","v1.0.395","v1.0.396","v1.0.397","v1.0.398","v1.0.399","v1.0.400","v1.0.401","v1.0.402","v1.0.403","v1.0.404","v1.0.405","v1.0.406","v1.0.407","v1.0.408","v1.0.409","v1.0.410","v1.0.411","v1.0.412","v1.0.413","v1.0.414","v1.0.415","v1.0.416","v1.0.417","v1.0.418","v1.0.419","v1.0.420","v1.0.421","v1.0.422","v1.0.423","v1.0.424","v1.0.425","v1.0.426","v1.0.427","v1.0.428"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2017-16941.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
