Description
Pheditor is a single-file editor and file manager written in PHP. From version 2.0.1 to before version 2.0.6, Pheditor ships with a hardcoded default password admin (SHA-512 hash stored at pheditor.php:11). There is no mechanism to force a password change on first login. Any deployment using the default credentials grants an attacker full access to the file editor, file upload, and terminal features, enabling arbitrary file read/write and remote code execution. This issue has been patched in version 2.0.6.
