Summary

Yii 2: Local file inclusion via view parameter name collision

Details

Yii 2 is a PHP application framework. Versions 2.0.54 and prior contain flawed logic in the core view rendering method View::renderPhpFile() that leads to Local File Inclusion. The function calls extract($params, EXTR_OVERWRITE) before the require statement that loads the view file. As a result, a caller-controlled file key in the $params array overwrites the internal local variable specifying which file to include, potentially enabling RCE if an attacker can write PHP files through a separate primitive, as well as information disclosure. This issue has been fixed in version 2.0.55.
