baserCMS is a website development framework. Prior to version 5.2.3, the application's restore function allows users to upload a .zip file, which is then automatically extracted. A PHP file inside the archive is included using require_once without validating or restricting the filename. An attacker can craft a malicious PHP file within the zip and achieve arbitrary code execution when it is included. This issue has been patched in version 5.2.3.

CVE-2025-32957 [HIGH] baserCMS has Unsafe File Upload Leading to Remote Code Execution (RCE)
baserCMS has Unsafe File Upload Leading to Remote Code Execution (RCE)
### Details
The application's restore function allows users to upload a `.zip` file, which is then automatically extracted. A PHP file inside the archive is included using `require_once` without validating or restricting the filename. An attacker can craft a malicious PHP file within the zip and achieve arbitrary code execution when it is included.
Vector: Malicious ZIP upload + insecure `require_once`
### PoC
1. Restore backup
1. Load file shell (insecure `require_once`)
### Impact
Remote Code Execution (RCE)
