MITRE ATT&CK Enterprise TechniquesAI

T1189 Drive-by Compromise Initial Access
Adversaries may gain access to a system through a user visiting a website over the normal course of browsing.
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.
T1203 Exploitation for Client Execution Execution
Adversaries may exploit software vulnerabilities in client applications to execute code.
Why these techniques?

The DOMPurify nesting-based mXSS vulnerability enables bypassing client-side HTML sanitization, allowing arbitrary JavaScript execution in victims' browsers via reflected or stored XSS on public-facing web applications with no privileges or user interaction required beyond page access.
