⚠️ Risk & Real-World Impact

🔴

Worst Case

Full server compromise through local file inclusion leading to remote code execution, sensitive file disclosure (including configuration files with database credentials), and complete site takeover.

🟠

Likely Case

Information disclosure of sensitive server files (wp-config.php, /etc/passwd, etc.), potential limited code execution depending on server configuration.

🟢

If Mitigated

Limited impact with proper file permissions and security controls, potentially only file read access without execution.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Exploitation requires no authentication and uses simple HTTP requests. Public proof-of-concept code is available.
