CVE-2023-45878 PoC — Gibbon 安全漏洞

Title:Gibbon 安全漏洞 (CVE-2023-45878)
Description:GibbonEdu Gibbon version 25.0.1 and before allows Arbitrary File Write because rubrics_visualise_saveAjax.phps does not require authentication. The endpoint accepts the img, path, and gibbonPersonID parameters. The img parameter is expected to be a base64 encoded image. If the path parameter is set, the defined path is used as the destination folder, concatenated with the absolute path of the installation directory. The content of the img parameter is base64 decoded and written to the defined file path. This allows creation of PHP files that permit Remote Code Execution (unauthenticated).

Gibbon LMS versions 25.0.1 and earlier are vulnerable to an Arbitrary File Upload that can lead to Remote Code Execution (RCE). The issue stems from the rubrics_visualise_saveAjax.php endpoint, which, notably, does not require authentication. Because of this, unauthenticated attackers could potentially upload malicious PHP files and execute arbitrary code on the server.
