{"id":"CVE-2020-27387","details":"An unrestricted file upload issue in HorizontCMS through 1.0.0-beta allows an authenticated remote attacker (with access to the FileManager) to upload and execute arbitrary PHP code by uploading a PHP payload, and then using the FileManager's rename function to provide the payload (which will receive a random name on the server) with the PHP extension, and finally executing the PHP file via an HTTP GET request to /storage/\u003cphp_file_name\u003e. NOTE: the vendor has patched this while leaving the version number at 1.0.0-beta.","modified":"2026-04-02T05:12:19.320439Z","published":"2020-11-05T02:15:12.067Z","references":[{"type":"ADVISORY","url":"https://github.com/rapid7/metasploit-framework/pull/14340"},{"type":"FIX","url":"https://blog.vonahi.io/whats-in-a-re-name/"},{"type":"FIX","url":"https://github.com/ttimot24/HorizontCMS/commit/436b5ab679fd27afa3d99c023dbe103113da4fee"},{"type":"EVIDENCE","url":"http://packetstormsecurity.com/files/160046/HorizontCMS-1.0.0-beta-Shell-Upload.html"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/ttimot24/horizont-cms","events":[{"introduced":"0"},{"fixed":"436b5ab679fd27afa3d99c023dbe103113da4fee"}]},{"type":"GIT","repo":"https://github.com/ttimot24/horizontcms","events":[{"introduced":"0"},{"last_affected":"59c2843b5df2ac2e78b1d54db4e40dbe082cf233"},{"introduced":"0"},{"last_affected":"5aa34ac4e457a49b83f24a2969593c495f3ed9ad"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"1.0.0-alpha"},{"introduced":"0"},{"last_affected":"1.0.0-beta"}]}}],"versions":["v1.0.0-alpha","v1.0.0-alpha.2","v1.0.0-alpha.3","v1.0.0-alpha.4","v1.0.0-alpha.5","v1.0.0-alpha.6","v1.0.0-alpha.7","v1.0.0-alpha.8","v1.0.0-beta"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2020-27387.json","unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"1.0.0-alpha2"}]},{"events":[{"introduced":"0"},{"last_affected":"1.0.0-alpha3"}]},{"events":[{"introduced":"0"},{"last_affected":"1.0.0-alpha4"}]},{"events":[{"introduced":"0"},{"last_affected":"1.0.0-alpha5"}]},{"events":[{"introduced":"0"},{"last_affected":"1.0.0-alpha6"}]},{"events":[{"introduced":"0"},{"last_affected":"1.0.0-alpha7"}]},{"events":[{"introduced":"0"},{"last_affected":"1.0.0-alpha8"}]}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
