Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

Directly prevents SQL injection in /payroll/view_employee.php by requiring validation and sanitization of user inputs before database query construction.

prevent

Mandates timely identification, reporting, and correction of the specific SQL injection flaw documented in this CVE.

prevent

Limits the impact of successful SQL injection exploitation by enforcing least privilege on the application's database account, reducing confidentiality and integrity damage to payroll data.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1213.006 Databases Collection
Adversaries may leverage databases to mine valuable information.
T1565.001 Stored Data Manipulation Impact
Adversaries may insert, delete, or manipulate data at rest in order to influence external outcomes or hide activity, thus threatening the integrity of the data.
Why these techniques?

SQL injection in public-facing web app directly enables T1190 for remote exploitation; facilitates database data collection (T1213.006) and stored data modification (T1565.001) via malicious queries.
