⚠️ Risk & Real-World Impact
Worst Case
An attacker could upload malicious files to sensitive system directories, potentially leading to remote code execution, data exfiltration, or complete system compromise.
Likely Case
Authenticated users could place files in unintended locations, potentially overwriting existing files or creating backdoors for future exploitation.
If Mitigated
With proper file permission controls and input validation, impact is limited to file placement in non-critical directories.
🎯 Exploit Status
Exploitation requires authenticated access. The vulnerability is straightforward to exploit once authenticated.
