Attack Vector and Complexity

This flaw can lead to unauthorized information disclosure, affecting the confidentiality of sensitive data.

According to Microsoft’s Common Vulnerability Scoring System (CVSS) version 3.1, the vulnerability scores 5.9 overall and 5.2 in the base metrics.

CVE-2024-37985 is characterized by a local attack vector, meaning an attacker would need physical or remote access to the affected system to exploit it.

Despite this requirement, no privileges or user interaction are necessary for an attack to be successful, which increases the potential risk.

The attack complexity is rated high, indicating that exploiting this vulnerability requires advanced technical skills and knowledge.

The scope of this vulnerability is marked as “changed,” suggesting that successful exploitation could impact other components beyond the initially targeted system.

The primary concern here is confidentiality, which has a high impact. However, integrity and availability remain unaffected.

Currently, the maturity of the exploit code for CVE-2024-37985 is labeled as “unproven,” meaning that while exploitation has been observed in the wild, no publicly available exploit code has been confirmed.

Microsoft has released an official fix to address this vulnerability, urging users and organizations to apply updates promptly to mitigate potential risks.
