| शीर्षक | PluXml 5.8.22 Deserialization Vulnerability |
|---|
| विवरण | PluXml CMS version 5.8.22 and earlier contains a critical backend deserialization vulnerability that allows authenticated attackers to achieve remote code execution. The vulnerability stems from improper handling of user-controlled file parameters in the media management module (core/admin/medias.php), which triggers PHP stream wrapper processing during file operations. By uploading a malicious Phar archive disguised as an image file and then triggering deserialization through the file rename functionality using a phar:// protocol path, attackers can exploit a gadget chain in the bundled Guzzle HTTP library (FileCookieJar::__destruct() → save()) to write arbitrary PHP code to the server, resulting in remote code execution. |
