The file would be named using the id parameter, which could be prepended with \"../\" to perform directory traversal, and the file contents were populated via the ibsf parameter, which would be base64-decoded and written to the file. While the plugin added a .jpg extension to all uploaded filenames, a double extension attack was still possible, e.g. a file named shell.php would be saved as shell.php.jpg, and would be executable on a number of common configurations.", "severity": [ { "type": "CVSS_V3", "score": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H" } ], "affected": [], "references": [ { "type": "ADVISORY", "url": "https://nvd.nist.gov/vuln/detail/CVE-2021-38346" }, { "type": "WEB", "url": "https://www.wordfence.com/blog/2021/10/multiple-vulnerabilities-in-brizy-page-builder-plugin-allow-site-takeover" } ], "database_specific": { "cwe_ids": [ "CWE-22", "CWE-79" ], "severity": "HIGH", "github_reviewed": false, "github_reviewed_at": null, "nvd_published_at": "2021-10-14T16:15:00Z" } }
