| 标题 | dedecms V5.7.118 Command Injection |
|---|
| 描述 | A vulnerability exists in DedeCMS V5.7.118 backend that allows authenticated administrators to write arbitrary PHP files to the server. The `tpl.php` file's `savetagfile` function writes user-supplied content directly to `.lib.php` files in the `include/taglib/` directory.
Although the application implements malicious code detection (Lines 31-61), this protection can be bypassed using PHP's ReflectionFunction API and php://input stream wrapper, leading to Remote Code Execution (RCE).
