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.
Why these techniques?

Direct remote SQL injection in a web application (update_out_standing.php via unauthenticated 'sid' GET parameter) maps to exploitation of a public-facing or network-accessible application for initial access and limited data manipulation.

Confidence: HIGH · MITRE ATT&CK Enterprise v18.1
