This type of vulnerability allows attackers to upload malicious files to the server, potentially leading to remote code execution (RCE), data exfiltration, or other severe impacts.

Severity Evaluation:

• Base Score: 10.0 (Critical)
• Base Score Version: CVSS 3.1
• Base Score Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H

The CVSS score of 10.0 indicates the highest level of severity. The vector string details the following:

• Attack Vector (AV): Network (N)
• Attack Complexity (AC): Low (L)
• Privileges Required (PR): None (N)
• User Interaction (UI): None (N)
• Scope (S): Changed (C)
• Confidentiality (C): High (H)
• Integrity (I): High (H)
• Availability (A): High (H)

This vulnerability is highly exploitable and can cause significant damage if not addressed promptly.
