|---|
| Mô tả | DedeCMS V5.7.118 backend file upload functionality contains a remote code execution vulnerability. The file uploads/dede/file_manage_control.php invokes include/uploadsafe.inc.php for upload security checks. An attacker can use non-UTF-8 byte prefix (\xfe\xff\xe0) to cause json_encode() to return FALSE, thereby bypassing the PHP tag sub-check on lines 87-104. Simultaneously, the backtick (`) operator is not a function name and bypasses the cfg_disable_funs regex match (line 73), enabling command execution. This vulnerability only requires administrator login privileges with no special configuration needed. |
