CVE-2025-47954 is a vulnerability classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command, commonly known as SQL Injection) affecting Microsoft SQL Server 2022 (GDR), specifically version 16.0.0. The flaw arises because the software fails to properly sanitize or neutralize special characters in SQL commands, allowing an attacker who already has some level of authorized access to inject malicious SQL code. This injection can be performed remotely over the network without requiring user interaction, making exploitation relatively straightforward (low attack complexity). Successful exploitation enables the attacker to escalate privileges within the SQL Server environment, potentially gaining administrative control over the database. This can lead to unauthorized data disclosure, data manipulation, or denial of service by corrupting or deleting data. The CVSS v3.1 score of 8.8 reflects a high severity, with full impact on confidentiality, integrity, and availability. Although no public exploits have been reported yet, the vulnerability is critical due to the widespread use of Microsoft SQL Server in enterprise and governmental infrastructures. The vulnerability was reserved in May 2025 and published in August 2025, indicating recent discovery and disclosure. No patches are currently linked, so organizations must monitor for updates from Microsoft. The vulnerability highlights the risks of insufficient input validation in database query processing and the importance of applying security best practices in SQL Server deployments.

For European organizations, the impact of CVE-2025-47954 can be severe. Microsoft SQL Server is widely used across Europe in sectors such as finance, healthcare, government, and critical infrastructure. Exploitation could lead to unauthorized access to sensitive personal data protected under GDPR, resulting in legal and financial repercussions. Privilege escalation within SQL Server could allow attackers to manipulate or exfiltrate data, disrupt business operations, or deploy ransomware. The network-based nature of the attack means that organizations with exposed SQL Server instances or insufficient network segmentation are particularly vulnerable. The compromise of critical databases could affect service availability and trust, impacting national security and economic stability. Additionally, the high severity and ease of exploitation increase the likelihood of targeted attacks or opportunistic exploitation once exploits become available. Organizations may face reputational damage and regulatory penalties if breaches occur due to this vulnerability.

To mitigate CVE-2025-47954, European organizations should implement the following specific measures: 1) Monitor Microsoft’s security advisories closely and apply patches or updates immediately once released for SQL Server 2022 (GDR) version 16.0.0. 2) Restrict network access to SQL Server instances by implementing strict firewall rules and network segmentation, limiting access only to trusted hosts and administrators. 3) Employ application-layer input validation and parameterized queries or stored procedures to prevent SQL injection at the application level. 4) Enable and review detailed SQL Server audit logs to detect anomalous or unauthorized SQL commands indicative of injection attempts. 5) Use least privilege principles for SQL Server accounts, minimizing permissions to reduce the impact of potential privilege escalation. 6) Conduct regular security assessments and penetration testing focused on SQL injection vulnerabilities. 7) Deploy Web Application Firewalls (WAFs) or database activity monitoring tools that can detect and block SQL injection patterns. 8) Educate developers and DBAs on secure coding and configuration practices to prevent similar vulnerabilities. These targeted actions go beyond generic advice by focusing on immediate containment, detection, and prevention tailored to this specific vulnerability and environment.
