Yii 2: Local file inclusion via view parameter name collision
Quick fix
GHSA-5vpg-rj7q-qpw2 — yiisoft/yii2: upgrade to the fixed version with the command below.
composer require yiisoft/yii2:^2.0.55Details
The core view rendering method `View::renderPhpFile()` calls `extract($_params_, EXTR_OVERWRITE)` before the `require` statement that includes the view file. A caller-controlled parameter named `_file_` in the `$params` array overwrites the internal local variable that specifies which file is included — enabling a Local File Inclusion primitive.
### Impact
- Local File Inclusion (arbitrary file read via non-PHP files) - Potential RCE if attacker can write PHP files via a separate primitive - Information disclosure
### Patches
2.0.55
### Workarounds
No.
