This vulnerability allows for elevation of privilege, which is a critical issue as it can lead to unauthorized access to sensitive information and system resources.

Severity Evaluation:

• Base Score: 9.8 (Critical)
• Base Score Version: 3.1
• Base Score Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

The CVSS score of 9.8 indicates a critical vulnerability. The vector string breaks down as follows:

• AV:N (Attack Vector: Network) – The vulnerability can be exploited remotely over the network.
• AC:L (Attack Complexity: Low) – The attack requires low complexity to exploit.
• PR:N (Privileges Required: None) – No privileges are required to exploit the vulnerability.
• UI:N (User Interaction: None) – No user interaction is required to exploit the vulnerability.
• S:U (Scope: Unchanged) – The vulnerability does not change the security scope.
• C:H (Confidentiality: High) – There is a high impact on confidentiality.
• I:H (Integrity: High) – There is a high impact on integrity.
• A:H (Availability: High) – There is a high impact on availability.
