CVE-2024-37335 is a heap-based buffer overflow vulnerability classified under CWE-122, discovered in Microsoft SQL Server 2017 (GDR), specifically version 14.0.0. The vulnerability resides in the Native Scoring component, which is used for machine learning model scoring within SQL Server. An attacker with low privileges can remotely trigger this vulnerability without requiring user interaction, leading to remote code execution (RCE). The flaw allows an attacker to overwrite heap memory, potentially enabling arbitrary code execution with the privileges of the SQL Server service account. The vulnerability has a CVSS 3.1 base score of 8.8, indicating a high level of severity due to its network attack vector, low attack complexity, no user interaction, and high impact on confidentiality, integrity, and availability. Although no public exploits are currently known, the vulnerability's characteristics make it a prime target for threat actors once exploit code becomes available. The lack of an official patch at the time of publication necessitates immediate mitigation efforts to reduce exposure. This vulnerability affects critical database infrastructure, which often hosts sensitive enterprise data and supports business-critical applications.

The impact of CVE-2024-37335 is substantial for organizations worldwide that rely on Microsoft SQL Server 2017 (GDR) version 14.0.0. Successful exploitation can lead to complete system compromise, allowing attackers to execute arbitrary code remotely, steal or manipulate sensitive data, disrupt database availability, and potentially pivot to other internal systems. Given SQL Server's widespread use in enterprises, government agencies, and critical infrastructure, this vulnerability poses a significant risk to data confidentiality, integrity, and availability. Attackers exploiting this flaw could cause severe operational disruptions, data breaches, and financial losses. The vulnerability's remote exploitability without user interaction and low privilege requirements increase the likelihood of successful attacks, especially in environments with exposed SQL Server instances or insufficient network segmentation. Organizations that fail to address this vulnerability promptly may face targeted attacks, data exfiltration, ransomware deployment, or destruction of critical data assets.

1. Apply official patches from Microsoft immediately once they become available for SQL Server 2017 (GDR) version 14.0.0 to remediate the vulnerability. 2. Until patches are released, restrict network access to SQL Server instances by implementing strict firewall rules and network segmentation, limiting exposure to trusted hosts only. 3. Disable or restrict the Native Scoring feature if it is not required for business operations to reduce the attack surface. 4. Monitor SQL Server logs and network traffic for unusual activity indicative of exploitation attempts, such as unexpected heap memory errors or anomalous remote connections. 5. Enforce the principle of least privilege for SQL Server service accounts to minimize the impact of potential exploitation. 6. Conduct regular vulnerability assessments and penetration testing focused on SQL Server environments to identify and remediate related weaknesses. 7. Maintain up-to-date backups of critical databases to enable recovery in case of compromise. 8. Educate IT and security teams about this vulnerability and the importance of timely patch management and network controls.
