CVE-2024-7342Public exploitNetwork attack vector

Stored XSS via permitted XML file uploads

Published Aug 1, 2024 · Updated Aug 1, 2024

Stored XSS in Baidu UEditor 1.4.3.3 allows remote attackers to upload script-bearing XML files through the PHP upload endpoint. The default fileAllowFiles list admits .xml and .swf content, and controller.php stores accepted upfile submissions under a web-accessible upload path. Exploitation requires the PHP backend, an unchanged allowlist, and user interaction with the stored file; the resulting script runs in the file's web origin.
