CVE-2023-1044Public exploitNetwork attack vector

Authenticated code execution via unchecked editor file path

Published Feb 26, 2023 · Updated Aug 2, 2024

Relative path traversal in MuYuCMS 2.2 allows remote authenticated users to read or overwrite server files through /editor/index.php. The get_file and save_file actions accept the file_path request parameter as a filesystem path without constraining it to the template directory. A valid session is required; reading a file checksum enables overwriting PHP content and executing it with the web server's privileges.
