Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly prevents SQL injection exploitation by requiring validation of all information inputs to SQL commands in SQL Server.
Ensures timely remediation of the specific SQL injection flaw in SQL Server through patching as recommended by Microsoft.
Mitigates the impact of privilege escalation by enforcing least privilege, limiting damage even if low-privilege accounts are exploited.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
SQL injection directly enables exploitation for privilege escalation from low-privileged authenticated access to high-level database control.
NVD 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.
Deeper analysisAI
CVE-2025-53727 is an SQL injection vulnerability (CWE-89) affecting Microsoft SQL Server, stemming from improper neutralization of special elements used in an SQL command. Published on 2025-08-12T18:15:42.193, it carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its network accessibility, low attack complexity, and significant impacts across confidentiality, integrity, and availability.
The vulnerability enables an authorized attacker with low privileges (PR:L) to exploit it over the network without requiring user interaction. Exploitation allows privilege escalation, granting the attacker high-level access and potentially leading to unauthorized data access, modification, or disruption of SQL Server operations.
