CVE-2025-47954 is a high-severity SQL injection vulnerability (CWE-89) affecting Microsoft SQL Server 2022 (GDR), specifically version 16.0.0. The vulnerability arises from improper neutralization of special elements used in SQL commands, allowing an authorized attacker with some level of privileges to execute crafted SQL statements over the network. This improper sanitization enables the attacker to manipulate SQL queries, potentially leading to privilege escalation. The vulnerability does not require user interaction and can be exploited remotely with low attack complexity, given the attacker already has some privileges (PR:L). The impact on confidentiality, integrity, and availability is high, as successful exploitation can lead to unauthorized data access, modification, or deletion, and potentially full control over the database server. No known exploits are currently reported in the wild, but the vulnerability is publicly disclosed and rated with a CVSS 3.1 score of 8.8, indicating a critical risk if left unpatched. The lack of available patches at the time of disclosure increases the urgency for organizations to implement mitigations and monitor for suspicious activity. Given the widespread use of Microsoft SQL Server in enterprise environments, this vulnerability poses a significant threat to organizations relying on this database platform for critical applications and data storage.

For European organizations, the impact of CVE-2025-47954 can be severe. Microsoft SQL Server is widely deployed across various sectors including finance, healthcare, government, and manufacturing in Europe. Exploitation could lead to unauthorized access to sensitive personal data protected under GDPR, resulting in regulatory penalties and reputational damage. The ability to escalate privileges remotely means attackers could gain control over database servers, leading to data breaches, data corruption, or service disruptions. Critical infrastructure and public sector entities using SQL Server could face operational outages or data integrity issues, impacting public services and business continuity. Additionally, the cross-border nature of many European enterprises means that a compromise in one country could have cascading effects across multiple jurisdictions, complicating incident response and legal compliance.

1. Immediate deployment of any official patches or updates from Microsoft once available is paramount. 2. Until patches are released, implement strict network segmentation and firewall rules to limit access to SQL Server instances only to trusted hosts and administrators. 3. Enforce the principle of least privilege rigorously, ensuring that accounts accessing SQL Server have minimal necessary permissions to reduce the impact of potential exploitation. 4. Enable and monitor detailed SQL Server audit logs and network traffic for unusual or unauthorized SQL commands indicative of injection attempts. 5. Use Web Application Firewalls (WAFs) or database activity monitoring tools capable of detecting and blocking SQL injection patterns. 6. Conduct thorough code reviews and testing of applications interfacing with SQL Server to ensure proper input validation and parameterized queries are used, minimizing injection vectors. 7. Prepare and test incident response plans specific to database compromise scenarios to enable rapid containment and recovery.
