Description
Improper neutralization of special elements used in an sql command ('sql injection') in SQL Server allows an authorized attacker to elevate privileges over a network
AI Analyst Comment
Remediation
Apply vendor patches immediately. Review database access controls and enable query logging.
Description Summary:
A SQL injection vulnerability in Microsoft SQL Server allows an authenticated attacker to elevate privileges over the network.
Executive Summary:
A high-severity SQL injection vulnerability in Microsoft SQL Server enables authenticated attackers to escalate their system privileges, posing a significant risk to database integrity and confidentiality.
Vulnerability Details
CVE-ID: CVE-2025-47954
Affected Software: Microsoft SQL Server
Affected Versions: Microsoft SQL Server 2022 (CU 20) 16.0.0.0 up to 16.0.4210.1; Microsoft SQL Server 2022 (GDR) 16.0.0 up to 16.0.1145.1
Vulnerability: This is an improper neutralization of special elements used in an SQL command (CWE-89) that permits an authenticated user to perform unauthorized SQL operations. The vulnerability requires the attacker to have existing network access and low-level privileges to execute the injection.
Business Impact
Successful exploitation of this vulnerability allows an attacker to elevate privileges, potentially granting them administrative control over the database environment. Given the CVSS score of 8.8, this flaw represents a high risk of unauthorized data access, modification, or complete system compromise, which could lead to severe operational disruption and potential regulatory compliance failures.
Remediation Plan
Immediate Action: Update affected SQL Server instances to the patched versions specified in the Microsoft security update guide.
Proactive Monitoring: Audit database logs for unusual query patterns, particularly those involving unexpected syntax or attempts to access system tables by non-privileged accounts.
Compensating Controls: Ensure that database service accounts follow the principle of least privilege and utilize a Web Application Firewall or database firewall to filter malicious SQL syntax where applicable.
Exploitation Status
Public Exploit Available: No
Analyst Notes: As of August 13, 2025, there is no public information indicating active exploitation or a public proof-of-concept for this vulnerability. The flaw is inherently dangerous due to the potential for privilege escalation, though it remains restricted to authenticated users.
Analyst Recommendation
The severity of this vulnerability necessitates prompt attention to minimize the window of exposure. IT administrators should prioritize the deployment of the vendor-supplied patches to all affected SQL Server environments immediately to prevent unauthorized privilege escalation and ensure the continued security of database assets.
